May 23, 2022 Eye Surgery0

If you are considering LASIK eye surgery to get rid of your glasses or contact lenses, it is a great step. But are you anxious and doubtful, regarding ‘is LASIK surgery painful?’ It’s very natural to have these doubts because we all know how sensitive our eyes are and ‘surgery in the eyes’, itself sounds fearful. But the good news is that LASIK (Laser-Assisted In-Situ Keratomileusis) eye surgery is totally painless and you will be awake all through the procedure. It is one of the best-known, quick, safe, and most commonly performed eye surgery for correcting vision. If you ask anyone who has actually had this surgery ‘does eye surgery hurt?’, almost 100 % will say ‘NO’ to this.

Let us know through this article, some details about how this LASIK eye surgery works and does LASIK eye surgery hurt?

How does LASIK work?

LASIK eye surgery is a minimally invasive procedure that provides you with better vision without glasses or contact lenses. LASIK works by reshaping your cornea (The clear front surface of the eye which allows light to enter the eye and contributes most of the eye focusing power), thus correcting the eye focusing ability and hence improving your vision.

For normal eyes, the light rays entering the eye are focused in such a way that images are formed on the retina and you can see clearly. But with various vision problems described below vision becomes quite difficult.

  • Near-sightedness(Myopia): Distant vision is not clear because the cornea curves too sharply and the images are formed in front of the retina. The LASIK flattens the cornea, thus improving its focusing power and images start forming on the retina.
  • Farsightedness (Hyperopia): Near vision is poor because the cornea is very flat and the images are formed behind the retina. With the help of LASIK surgery, the cornea is curved and made steeper, thus correcting the vision.
  • Astigmatism: Where the cornea is uneven and both distant and near vision is disrupted. LASIK surgery smoothens the cornea and improves vision.

Before the surgery:

  • Your ophthalmologist will numb your eyes with a numbing solution so that you do not feel any pain or discomfort. This will clarify your doubt about ‘Does LASIK hurt?’
  • An instrument will help your eyes be wide open and a suction ring is placed before cutting the corneal flap. This might make you feel some pressure in your eyes.
  • Your eye surgeon will use a cutting laser to cut a small flap away from the front of your eye. This flap is folded back to allow them to access your cornea.
  • Then, using a controlled laser, your ophthalmologist will reshape your cornea according to your need.
  •  After reshaping, the surgeon will put the flap back in its place which heals without stitches.
  • The entire procedure takes around 20 minutes with actual surgery time which is not more than 5- 10 minutes.

Why Does LASIK Eye Surgery Seems Painful?

One of the most common fears of LASIK surgery is the thought of a ‘laser’ coming in contact with our eyes, which is the most delicate and sensitive organ of our body. Getting the surgery done on the eyes itself seems very frightening. When we understand the entire process of the LASIK surgery and come to know that a cut will be made, the flap will be cut, the corneal shape will be modified with some instrument. It seems dreadful and you may be anxious and have a question in mind that ‘Is laser surgery painful’? Also, in the past when technology was not much advanced, this surgery might be causing some pain and discomfort, which people relate to even now. But the fact is, that with so much technological advancement and most modern techniques and equipment, LASIK surgery has become very quick and completely painless. Therefore, be very clear about it, and never have doubts like ‘Does Photorefractive keratectomy (PRK) hurt?’

Does LASIK Eye Surgery Really hurt?

LASIK surgery does not hurt or cause any pain, during or immediately after the procedure, as medications and numbing solutions are given prior to the surgery to alleviate any discomfort during the surgery. Only some pressure might be felt during the procedure.

Many times eye surgeons also prescribe medications to relax, in case you feel too anxious. After the laser reshapes the cornea, the flap is replaced and this serves as a natural bandage to facilitate healing. Now, you may be wondering ‘Does LASIK hurt after surgery?’

After the LASIK surgery, there may be a few after-effects like:

  • Mild discomfort.
  • Itching.
  • Mild pain.
  • Watery eyes etc.
  • Dry eyes.
  • Blurry vision.
  • Haziness

All these usually occur after several hours of surgery, but these are temporary, and usually resolve within a few days.  You must be very regular with the medications and eye drops that your surgeon prescribes, so as to avoid any infection and speed up healing. Therefore, you need not even think of ‘Does eye laser treatment hurt?’

In very rare instances, if you experience severe pain, redness, swelling, or any kind of unusual signs and symptoms, immediately contact your eye surgeon.

FAQs

  1.     What are the aftercare tips to follow after LASIK eye surgery?
  • Try to keep your eyes closed and rest for some hours immediately after the surgery.
  • Wear a protective eye shield while sleeping at least for the first 5 nights to avoid accidental injury and irritation to your eyes.
  • Avoid going into bright sunlight and dusty places and always wear sunglasses to protect your eyes.
  • Avoid eye makeup for a few days.
  • Apply your eye drops and take medications very regularly as prescribed by your eye surgeon.
  • Keep your follow-up appointments very regular, even if you are feeling perfect.
  1.     Is LASIK surgery completely safe?

The success rate of LASIK eye surgery is more than 90% and mostly people get perfect vision, 8 out of 10 do not need glasses or contact lenses after the procedure. Minor temporary side effects may be there which go off gradually and can be managed with medications. Only 10% may have risks like:

  • Recession.
  • Prolonged dry eyes.
  • Under correction.

These might need the use of lubricating eye drops for a prolonged-time period or another surgery for proper correction. Your eye surgeon will guide you on this. Less than 1% may have very serious side effects like vision loss.

At present, LASIK eye surgery is the most common and the best-known refractive laser surgery to correct issues with vision. The LASIK surgery is performed by a LASIK eye surgeon, who uses the laser to correct refractive errors, i.e., when the eye does not refract (bend) the light properly, resulting in blurred vision. It works on the concept of correcting the shape of the cornea so that it is better able to refract light helping in improving vision.

Good candidates for LASIK surgery are individuals suffering from vision problems like Myopia (Nearsightedness), Hypermetropia (Farsightedness), and Astigmatism (change in the shape of eyes). Individuals over 18 years of age with healthy corneas and no other eye disorders are the Best LASIK candidates. A LASIK eye surgery would help them to permanently improve their vision and reduce their dependency on glasses/ contact lenses.

However, LASIK eye surgery for Cataracts is not a recommendation. In cataracts, the lens inside the eyes becomes cloudy, and LASIK will not correct the blurriness caused due to this reason.

Any individual with optical abnormalities like dry eyes, glaucoma, and health conditions like diabetes, does not qualify for the LASIK candidate test.

IF YOU HAVE HEALTHY EYES

Healthy eyes are the most important criteria if one wishes to undergo LASIK eye surgery. Any kind of eye injury or conditions like eye infections, conjunctivitis, and dry eyes can adversely affect the surgery as well as the healing process.

The presence of cataracts and long-standing glaucoma are conditions that are contraindications for LASIK eye surgery.

The cornea of the eyes should be thick and healthy because LASIK eye surgery is based on reshaping the cornea for better vision. LASIK might not be advisable if the cornea is too thin or misshaped due to any disease.  

Large pupils may also put the individual at risk of encountering halos and glare, especially at night. A good long-standing prescription for farsightedness or nearsightedness makes an individual a good candidate for LASIK eye surgery. Results of LASIK surgery with very high refractive errors are less predictable and may result in impaired vision.

Your Age Should Be Above 18

Ideally, individuals between 18-and 40 years of age are the best candidates for LASIK eye surgery. Before 18 years of age, the eyes continue to change and grow. During this period, eye surgery for vision correction is not advisable as there is a possibility of a change of prescription. If the surgery is performed during this period, the effects of the surgery may be temporary, and the individual might have to use glasses as soon as the prescription changes.

According to US FDA, individuals over 18 years of age are considered good candidates for LASIK eye surgery. By this time, the refraction stabilizes, and in most cases, the person’s refraction/ prescription does not change after this age. For a successful result, the prescription needs to be stable for at least 1 year.

However, the physiology of the eye changes after 40 years of age. Around that age, most people develop the need for glasses for reading. LASIK eye surgery does not treat this condition and therefore is not recommended for this age group.

You Should Have Stable Vision

Stable vision/ refraction is necessary because LASIK eye surgery aims to improve vision. The purpose of surgery is to improve vision and make the refraction/ vision correction results more stable, long-lasting, and effective. The refraction error to be corrected needs to be stable for at least one year prior to surgery.

If LASIK eye surgery is performed in unstable refraction, the individual might be saddled with glasses or require multiple surgeries.

Also, it’s quite possible that if the prescription is unstable, there may be a disease or some underlying eye infection, making LASIK eye surgery a contra-indication.

If You’re in Overall Good Health

Not everyone is a good candidate for LASIK eye surgery. There are certain physiological conditions in which this surgery is contraindicated.

Individuals suffering from auto-immune disorders like diabetes, arthritis, cataract, and glaucoma are not suitable candidates for LASIK eye surgery. These conditions may result in dry eyes. Under such circumstances, the healing process is delayed and may make the individual more prone to post-surgery infections. Any kind of eye infection and injury also contraindicates LASIK eye surgery. It may make the healing process delayed and lead to corneal scarring.

LASIK eye surgery should not be performed in individuals suffering from dry eye syndrome. Already existing syndrome might lead to discomfort in the eyes and may worsen the already existing syndrome. This might delay the healing process, which might be detrimental in the future.

Conditions like pregnancy and lactation are not the right conditions for undergoing LASIK eye surgery. Hormonal fluctuations might cause changes in vision (nearsightedness/ astigmatism) and dry eyes. Undergoing surgery during this condition might lead to delayed healing, and dryness might make the eyes uncomfortable. Also, the medications prescribed after eye surgery might harm the fetus.

Certain drugs like steroids might interfere with the results and delay the healing process after  LASIK eye surgery. Drugs prescribed for Acne may cause increased dryness and cornea scarring after LASIK.             

Your Current Eye Prescription Should be Stable

Before undergoing LASIK eye surgery, the current eye prescription should be stable. Any instability in the prescription will make the surgery difficult. The result of the surgery would also be not accurate, and the individual may end up with glasses/ lenses for proper vision.

The individual must have a stable prescription for at least one year prior to surgery to get the maximum benefit of surgery.

TAKE AWAY

LASIK eye surgery is a convenient and successful procedure, but the preparation for surgery and recovery after surgery requires patience.

Age, healthy being, and healthy eyes are the most important criteria for any individual who wants to undergo LASIK. However, with technology changing every day, age might just be a number.    

Most LASIK eye surgery procedures are successful and give effective results, but before undergoing any such procedure, the individual must be aware of the potential risks, side effects, and complications. 

One should be able to properly weigh their eligibility and expectation while deciding on LASIK eye surgery. A thorough eye examination from an ophthalmologist to decide eligibility for the surgery is of utmost importance before deciding to opt for the same. 

FREQUENTLY ASKED QUESTIONS

  •  How do I know that I am a candidate for LASIK eye surgery?

Before deciding to undergo LASIK eye surgery, you will have to go and meet an ophthalmologist. The doctor will do an initial check-up regarding the condition of your cornea, pupil, and extent of your refractive error. The doctor would be better able to guide you about your eligibility, benefits, risks, and complications involved.

In general

  • You should be above 18 years of age,
  •  Should not be suffering from any chronic ailment
  • Should not be pregnant or breastfeeding
  • Have healthy eyes
  • Have a stable prescription for at least one year prior to surgery.
  • What exactly is the procedure for LASIK eye surgery?

The main aim of LASIK eye surgery is to change the shape of your cornea so that it is better able to refract light, thus focusing better on the retina and improving vision.

Following are the steps involved in the surgery:

  • The doctor will examine your eyes to ensure that they are healthy enough to be operated on.
  •  A sedative in the form of eye drops would be introduced in your eyes.
  • The doctor will then use a Femtosecond laser to make a thin circular flap in your cornea. This flap, when folded back, will provide access to the underlying cornea.
  • Small amounts of the tissue would be removed from the cornea to reshape it with the help of a laser with UV beams.
  • In case you are farsighted, the laser will create a deeper cornea. In case you are nearsighted, the laser will create a flat cornea.
  • The flap would then be laid back, and the cornea would be allowed to heal naturally. 
  •  Is LASIK eye surgery time-consuming and painful?

Fortunately, NO. This surgery is not time-consuming and is not painful at all. Before the surgery, the surgeon will put a numbing eye drop in your eyes so that you don’t feel any pain. However, you might feel certain pressure during the procedure, but that goes away as you recover.

  • When will I see the result of  LASIK eye surgery?

Immediately after the surgery, your vision will improve. You will start seeing those things clearly that you could not earlier. Initially, things might appear a little hazy, but the vision improves as the eyes recover.

  • What are the side effects/ risk involved with LASIK eye surgery?

The side effects of this surgery are very rare. Some people might experience certain side effects like:

  •  An impaired nighttime vision such as halos  and glare while driving
  • Dry eyes
  •  Inflammation and infection

Did you know that almost 10% of corneal blindness can be treated with corneal implants? This miraculous treatment, also known as keratoplasty, replaces the damaged cornea with that of the corneal tissue of a donor. 

The cornea enables clear vision and is the large white dome-shaped surface of the eye. Along with damaged corneal replacement, corneal transplantations relieve pain associated with corneal infections and damage. Some of the reasons to perform a cornea transplant include:

  • Corneal ulcers or Infectious keratosis
  • Corneal scarring
  • Hereditary conditions like Fuch’s dystrophy
  • An infection, injury, or swelling of the cornea
  • Thinning and breakdown of the cornea
  • Previous transplant graft rejection

Corneal transplant surgeries are highly successful in restoring vision. However, like any other surgical procedure, carry a minute iota of risk or complications. Nevertheless, reinforcing an indispensable part of your eye is worth taking the risk as its success rate in prominent eye clinics stands around 95%. 

With progressive technology in organ transplantation, corneal transplantation has developed over the years. And the corneal transplant cost in India has also become cost-effective with no compromise on the quality of the transplantation process. 

This article explores corneal transplant costs in India while delving into the various factors affecting its pricing and more.  

Corneal Transplant Cost in India 

The human eye is embedded with a natural lens, allowing the light to enter and help us to see. The eye lens is covered by a transparent, dome-shaped, white covering called the cornea. The cornea protects the eyes from dirt, germs, and harmful radiation. The cornea also helps focus the light entering the eye, enabling clear vision.  

The damage or infection of the corneal region obstructs the path of light and thus can disrupt normal vision. Cornea transplants can effectively help re-establish the focussing of light while restoring vision. During the corneal transplantation surgery, the eye specialists replace the damaged or infected cornea with donor corneal tissues.

The cost of a cornea transplant in India ranges from Rs. 50,000 to 1,50,00 per eye (sometimes inclusive of the eye checkups and consultation). The corneal transplant cost depends on the city, hospital, and type of corneal transplant performed. 

Types of Corneal Transplant and their Cost 

The cornea is a five-layered tissue. Sometimes, partial or the entire thick cornea is replaced depending on the condition and extent of the damage. Thus, deciding the type of corneal transplants.

  • Penetrating keratoplasty (PK): It is a full-thickness corneal replacement surgery where all the layers of the cornea are removed and replaced with the donor corneal tissue. This conventional method requires a longer healing time while is considered for significant bulging or damage of the cornea.
  • Deep anterior lamellar keratoplasty (DALK): In DALK or Partial Thickness Corneal Transplant, the middle and outer damaged corneal layers are replaced with corneal tissues. This procedure treats corneal scarring that has not affected the inner layers.  
  •  Endothelial keratoplasty (EK): There are two types of EK’s. 

One is Descemet’s stripping endothelial keratoplasty (DSEK or DSAEK), where one-third thick cornea is removed and replaced. 

Second is Descemet’s membrane endothelial keratoplasty (DMEK), where the endothelium and the Descemet’s membrane are replaced with that of the donor. 

DSAEK involves thicker corneal replacement than DMEK. DMEK is more complicated and needs finesse but assures quick recovery. A most preferred option for hereditary Fuch’s dystrophy and only inner corneal damage. 

The overall corneal transplant cost in India starts from Rs. 50,000 averaging nearly Rs. 70,000 for each eye. And the maximum cost for cornea replacement of a single eye can go up to Rs. 1,50,000.  

Factors Affecting the Cost of Corneal Transplant in India

Corneal transplantation is a remunerative and effective procedure. The corneal transplant cost in India is subjected to change based on some of the influencing factors such as;

  1. Consultation fees of the doctor
  2. Admission fees of the hospital
  3. Hospitalization charges
  4. Type of donor tissue replaced
  5. Type of the keratoplasty performed
  6. The extent of infection and damage of the cornea
  7. The associated medical condition of the patient (if any)
  8. Post operational complications involved
  9. Lab tests or examinations- X-rays, ECG, blood tests, and others.

FAQs 

  • What is the recovery time for a cornea transplant?

Generally, corneal transplants are known to give faster results. It may take at least a year to recover completely from cornea transplantation. However, one can experience improved vision and resume their daily activities apart from heavy weight lifting or strenuous activities after one or two weeks post corneal replacement surgery. 

  • How long does a replaced cornea last?

The cornea transplant surgery is quite effective in restoring a clear vision. It is observed that a replaced cornea can last for a lifetime, provided the donor perfectly matches the recipient. 

  • What is the success rate of a cornea transplant surgery in India?

The success rate of a cornea transplant depends on some of the factors like:

  • Age of the patient
  • Associated medical conditions (if any)
  • Experience and expertise of the surgeon
  • Type of surgery performed

However, keeping all the above factors in view, the top eye clinics in India have a success rate of nearly 95%. 

  • Will there be any discomfort after cornea replacement surgery?

Post corneal replacement surgery, the eyes may get red, irritating, and sensitive to light for a while. The patient may have slight discharge or discomfort for a few days after surgery that is manageable with medications and pain killers. 

Take Away 

The cornea is a crucial part of the eye that focuses the light enabling proper vision. The damaged or injured cornea can disrupt light and visual impairment. Owing to the advancement in technology and eye treatments, cornea transplants have come a long way from conventional methods of all-layer corneal replacement to the new cutting-edge procedures of deep lamellar transplant involving expertise and finesse. 

The cost of a corneal transplant in India ranges anywhere between Rs. 50,000 to Rs. 1,50,000 and are subject to differ due to various reasons. Dr. Deepa Gupta is a highly experienced eye specialist in lamellar transplant surgeries like DSEK and DALK. Her comprehensive approach to the condition and state-of-the-art technology she endures will help you retrieve improved vision at affordable pricing.  

FAQs

What is the Cost of a Corneal Transplant?

A healthy cornea is vital for good vision, and if it is damaged, it can become swollen, scarred, and severely affected, distorting the vision and leading to vision loss. Whether the cornea damage is due to injury, infection, or disease, it can be treated effectively with a cornea transplant. For those who can’t see well because of this problem, a corneal transplant or keratoplasty is the only perfect option to restore their vision. It is a corrective surgery, known as keratoplasty, that removes the existing cornea and replaces it with another. The procedure effectively brings back vision, lessens the pain, and improves the look of the damaged cornea.

The cost of corneal transplant in India varies and depends upon many factors like the severity of the condition, type of procedure, preparation of tissue grafts, surgeon’s experience, and many other additional costs associated with the surgery. The overall corneal transplant treatment cost in India ranges between Rs. 50,000 to Rs. 1,50,000 for each eye. However, the cost can be reduced depending on your health insurance coverage.

What Factors Determine the Cost of DSAEK Surgery?

DSAEK is a type of cornea surgery that involves thicker corneal replacement. It is considered a relatively new procedure that has revolutionized the treatment of disorders in most layers of the cornea. DSAEK can be performed in people with complex ocular anatomy, i.e., prior corneal transplant, history of glaucoma, or if they have prior trauma. The best part is that this type of surgery has easier post-operative recovery, and patients have a good quality of vision afterward, as many attain a vision of 20/30 or even better. However, many factors determine the overall cost of the DSAEK surgery.

The overall charges for DSAEK Surgery cost or any keratoplasty range from Rs 50,000 and above. If other procedures are also required, charges may go up to Rs 70,000 to Rs 1,50,000 per eye. However, it is vital to understand the actual cost of the DSAEK, which can depend on many factors, such as the type of transplant, the specific healthcare facility chosen, and any additional medical expenses. To get the most accurate pricing information, it’s recommended that you consult with the best eye specialist, as costs may differ between providers.

What’s the recovery time for DSAEK vs. Traditional Transplant?

DSAEK eye surgery is a type of corneal Transplant surgery in which most of the cornea is replaced by preserving the thin posterior membrane of the eye, i.e., The Descemet membrane and endothelium. It is the best alternative to PKP. However, DSAEK Corneal Transplant is more complex and challenging than other corneal surgeries. The recovery time post-DSAEK can vary from patient to patient and depends upon various factors; however, most patients notice an improvement in vision within several weeks to months. Generally, all types of corneal transplants are known for faster results. It may take a year to recover entirely from corneal transplantation. People can resume their normal activities in one to two weeks. They just have to avoid heavy weight lifting or strenuous exercises post-surgery.

A high number of study data have significantly addressed the effect of environmental pollution on the ocular surface. Any form of impact to our eye ultimately compromises our ability to see. 

Though our eyes have inbuilt ability to protect themselves, there are defects on the micro-structure of the eye, such as the complex conditions that affect the curvature of cornea or the eyeball. They need professional treatment from experienced eye surgeons to fix the curvature and improve your vision. 

The most common or widely performed treatment to correct vision problems is the lasik eye surgery. However, advanced forms of lasik surgery, such as the contoura lasik surgery is technically optimised for a more individualised treatment. 

Both Lasik and contoura vision treatments deals with the following vision problems: 

  • Nearsightedness (myopia): A condition where it is difficult to see distant objects due to the sharp curvature of the cornea or a slightly longer eyeball. 
  • Farsightedness (hyperopia): A condition where the nearby objects are blurred as light gets focussed behind the retina owing to a shorter eyeball or flattened cornea. 
  • Astigmatism: This condition affects both near and distant vision as the cornea flattens or curves unevenly. 

In this article, we will dwell into an advanced form of lasik surgery and contoura vision surgery that has proven beneficial to many and know the difference between them.

1. What is Contoura Vision Eye Surgery? 

Many times the effect of uneven curvature of cornea is corrected through lens and glasses. However, many opt to get rid of their glasses by undergoing laser surgery that precisely removes a tiny amount of corneal tissue to correct the refraction of light for a more focussed vision. Contoura lasik surgery is a type of laser surgery where an uneven cornea is shaped to focus light precisely on the retina and improve vision. It is an advanced form of laser surgery which has many technological capabilities in mapping the cornea for better surgical outcome.

As topography and microstructure of the eye is unique to a person, not all patients come with a single defect in the cornea and hence, the treatment should be tailored to the needs of the patient. Contoura vision surgery does exactly this by taking into account the minute imperfections of corneal curvature mediated through the use of automated corneal topography or corneal curvature map of the eye. This is much more precise than the details obtained through prescription glasses or lenses. 

Contoura vision surgery cost in India varies with the expertise and infrastructure of the hospital. The estimated contoura vision cost in Delhi ranges from Rs. 95,000 to Rs. 1,15,000 for its treatment. The higher contoura vision cost in India is due to the added safety and improved visual outcome involved in the treatment.

2. What is Lasik Eye Surgery? 

The vision problems can be corrected through eyeglasses or contact lenses that refracts light and position it correctly on the retina and turn the previously blurred image into a clear one. Lasik eye surgery, on the other hand, works by reshaping your cornea so that light focuses on the focal point of the retina for a better vision. Lasik eye surgery is a safe and pain-free simple procedure where the patient’s vision is stabilised within 24 hours of surgery. Initially a cut is made on the corneal flap using a mechanical surgical tool to expose the inner cornea (called stroma). This is followed by reshaping the cornea by removing a microscopic amount of tissue using an excimer laser. 

The corneal topographer will precisely mark the shape of your cornea and adjust the excimer laser as per your prescription. In lasik treatment, the corneal mapping takes into account 200 points. More points are taken into account in the case of contoura vision surgery.  

Based on the technicality and treatment plan, the lasik eye surgery cost in Delhi varies in the range between Rs. 75,000 and Rs. 90,000.

3. What Is the Difference Between Contoura Surgery and Lasik Vision Surgery? 

Both contoura vision surgery and lasik surgery differs with the technical advancements and personalised treatment methodology. The difference in both the treatment procedures can be highlighted with the following points:

  • Contoura vision surgery has an advancement over lasik surgery in its ability to map 22,000 points on cornea using corneal topography and wavefront analysis, providing a customised procedure for the patients. Lasik surgery also uses corneal mapping, but it takes into account 200 points which is less compared to the contoura vision surgery.
  • The standard lasik surgery is mostly based on glasses or prescription lenses which is inferior to the technological advancement of contoura vision surgery. 
  • Contoura is an advanced surgery and it is not limited to vision correction. Rather, the technique is also used to treat abnormalities in cornea curvature.

Contoura vision surgery is approved by the US FDA for vision correction. It has enhanced diagnostic capabilities capable of providing personalised treatment for vision problems. 

4. Pros and Cons of Lasik and Contoura Vision Surgeries

How Many Types of LASIK Surgery?

LASIK surgery is the best treatment for correcting your vision problems if you suffer from nearsightedness, astigmatism, or astigmatism. There are different types of LASIK surgery, generally following the same procedure but may have different or more cutting-edge technology. LASIK eye surgery is successful with rare complications. However, the side effects of LASIK eye surgery are not permanent.

There are many advanced forms of LASIK surgeries owing to medical technological advancements. Some advanced forms of LASIK surgery are Femto LASIK and Contoura Vision. Both are advanced forms of LASIK surgery that utilize laser technology to correct vision. The main points that differentiate both are the method and technology used. The choice between the two Femto LASIK Vs Contoura Vision depends upon many factors; thus, it is best to consult an experienced ophthalmologist.

Femto LASIK Vs Contoura Vision – The Difference

Femto LASIK and Contoura Vision are advanced forms of LASIK surgery, which aim to correct refractive errors like myopia, hypermetropia, and astigmatism. Both kinds of LASIK surgeries differ in terms of the approach used in them to reshape the cornea.

About Femto LASIK

It is an advanced form of traditional LASIK that uses a potentially safer Femtosecond laser to create a corneal flap, leading to more precision. It is an advanced blade-free process. There are many benefits and side effects of Femto LASIK eye surgery side effects:

Benefits of Femto LASIK Surgery:

  • This surgery offers fast results.
  • It is very gentle on the corneal layer.
  • The procedure works precisely to create a consistent corneal flap.

Side effects include:

  • Shows a temporary decrease in tear production.
  • Sensitivity to light.
  • Experience minor fluctuations in vision.

About Contoura Vision

Also known as topography-guided LASIK, it takes customization to an updated level. The procedure uses detailed topographical mapping of a person’s cornea that guides the laser to reshape it. With this technique, your eyes will be scanned and mapped to create a custom treatment plan for the best possible results. There are many benefits and side effects of Contoura vision surgery:

Benefits include:

  • Reduction in your dependence on glasses.
  • Improved night visions.
  • Reduced dry eye symptoms.
  • Reduce the risk of developing cataracts. 
  • Enhanced color perception.
  • Treat many vision issues.

Side effects include:

  • Dry eyes 
  • Blurry vision
  • Double visions
  • Galre
  • Sensitivity to light
  • Eye pain

Which One to Choose?

Choosing between both depends upon many factors. Eye health is the main factor, as both techniques need some eye health. Eye specialists will first determine that your cornea should have sufficient thickness and that eyes should be free of diseases like glaucoma, eye dryness, etc. There is also a need for specific vision as Femto LASIK is done if your eyes are fine; if you have subtle irregularities, then Contoura Vision is preferred as it offers a better outcome by correcting issues.

If your job demands superior vision, then you should choose Contoura Vision, as it improves the quality of vision. Both have many benefits and side effects, so it is vital to discuss them with a doctor in advance. Among the two, the Contoura Vision surgery procedure is more expensive than Femto LASIK because of its advanced technology and additional testing that is included.

5. Takeaway

This brief discussion provides an overview of two types of vision correction surgeries – lasik surgery and contoura vision surgeries. Though both techniques have their own pros and cons, contoura has been effective for many patients where tissue damage is relatively less. 

For more information, contact Dr Deepa Gupta, the best eye specialist, with over 8 years of experience in several vision correction treatment techniques. She has published research works related to cataract and refractive surgeries.

Before deciding between the two, discuss all details with your ophthalmologist; however, both types of LASIK surgeries represent an advancement in the field of laser surgery, and both have outstanding results in treating refractive errors. Femto LASIK, on the other hand, is considered best because of its precision in creating the corneal flap, enhancing safety, and reducing complications.

On the other hand, Contoura Vision takes personalization to different heights by using detailed topographical mapping of the patient‘s cornea to guide the reshaping procedure if you seek the best eye specialist, conduit Dr Deepa Gupta, who has more than eight years of experience in correcting refractive errors.

6. FAQs 

1. Is Contoura vision better than lasik?

Contoura vision treatment provides 22,000 mapping points of the corneal curvature compared to lasik surgery which is limited to 200. This gives an advantage over lasik in better performance and effective correction of refractive error.

2. Is contoura vision surgery safe?

Countora vision surgery has a technical advancement over lasik surgery in mapping the corneal curvature, giving it substantial leverage over other techniques in providing better results and broader scope. Moreover, contoura vision surgery is approved by US FDA for its higher safety in vision correction procedure.

3. Are Femto LASIK and Contoura Vision Same?

However, both Femto LASIK and Contoura Vision are the types of LASIK surgery that aim to correct vision, but they are not the same. Contoura vision is a specific type of surgery that utilizes advanced mapping technology, and on the other hand, Femto LASIK uses a femtosecond laser to create the corneal flap.

Ageing brings along its inevitable changes that does not spare your eyes too ! Globally, cataract is one of the most common causes of treatable blindness. Irrespective of the aetiology of cataract, be it congenital, drug-induced, trauma-related or age-associated, cataract surgery is effective for all.

Many recent studies suggest an estimate for cataract surgery to be of around 65 lakh per year. Timely intervention and avoiding delays in cataract surgery curtails the chances of developing impaired vision. So, if that night driving is getting troublesome due to scattered light coming from opposite headlights or identifying a distant object is getting blur, you better not wait and watch !! Seek an ophthalmologist’s appointment at the earliest for “well begun is half done”.

1. WHAT HAPPENS IN CATARACT SURGERY?

In cataract surgery, cataract (meaning clouding of ocular lens) is removed from your eyes depending on the type of cataract diagnosed. The different types of cataract can be grouped as under:

  • Nuclear Cataract – problematic facial and colour discrimination
  • Cortical Cataract – sensitivity to light
  • Posterior subcapsular Cataract – visual difficulties in bright light which improves with dim light
  • Hypermature senile Cataract – severely challenged or complete loss of vision 
  • Congenital defects and white Cataracts – unable to see any degree of light

The severity of visual impairment dictates the technique for removal of cataract. You are advised not to eat or drink for 5-6 hours prior to surgery, when the cataract surgery is planned under general anaesthesia. With modern techniques, procedures are now being  performed under local or topical anaesthesia as well. Based on the difference in methodology, various cataract surgery types are opted by the operating surgeon:

  • Intracapsular Cataract Extraction (ICCE): involves removal of capsule and lens
  • Manual Extracapsular Cataract Extraction: 9 to 13 mm of incision is placed for removal of lens and placement of intraocular lens (IOL). Low cost procedure.
  • Manual Small-incision Cataract Surgery (MSICS): Externally 6.5 to 7 mm incision is placed in a V shape with internal length of incision being 9 to 11 mm, through which the lens is delivered out and IOL is placed. Allows for natural sealing of incision.
  • Phacoemulsification: An ultrasonic probe is introduced through a small incision of 2 to 3 mm. The probe emulsifies the lens which is then aspirated. It is followed by insertion of foldable IOL. Allows for self-sealing of wounds.
  • Femtosecond Assisted Laser Cataract Surgery (FLACS): Lens is defragmented and replaced with IOL by means of assisted laser technique.

Instructions for post-operative care along with medications are prescribed. You are advised for follow-up visits to keep a tab on the healing process.

2. HOW LONG DOES IT TAKE FOR THE EYE TO HEAL AFTER CATARACT SURGERY?

Advanced automated procedures have led to the advent of quicker surgeries. Laser assisted techniques require less than a minute for operating. With smaller incision techniques also, the surgery time is reduced remarkably compared to historical techniques of cataract removal. It typically takes not  more than an hour for the entire cataract surgery to be performed and the patient can be discharged soon. You must ensure to follow precautions after your cataract surgery in order to keep any potential risk at bay. 

Quicker surgery results in minimal postoperative risks and rapid recovery. Smaller to no incisions allows for natural wound healing.The vision is restored to almost full accuracy. You can witness your dreams with a clear vision almost as soon as you activate your plan of action.

3. WHAT CAN YOU EXPECT AFTER THE SURGERY?

While you may be thinking about what precautions you need to take after cataract surgery, we have the following points for you. 

  • Follow your post-operative instruction list as directed by the treating surgeon. 
  • You are prescribed topical corticosteroids, antibiotics and non-steroidal anti-inflammatory eye drops for 3 to 4 weeks.
  • It is recommended to be assisted with someone to the clinic and avoid self drive.
  • It is advisable to avoid any kind of strain to the eyes that puts pressure on the operated eye
  • Protective eyewears are recommended for use, in order to prevent exposure to dust and water.
  • Make a follow-up visit, in case of complications like- oedema, infection, bleeding, eyelid drooping or excessive pressure on the operated eye.

4. TAKE AWAY

Success rates of cataract surgery are quite high eliminating the chances of cataract blindness. Safety and efficacy of treatment in cataract surgery is of critical importance. High standards of care and precision in technique allows for remarkable accuracy. With corrected vision there is development of an improved sense of emotional and mental well-being. There is an overall decrease in mortality rate because of patients undergoing cataract surgery as it leads to lesser traffic crashes and reduced cases of unemployment, anxiety, injuries and hospital admissions. 

An eye check-up is recommended every 6 months for age groups 60 and above while annually for the younger generation.

Dr. Deepa Gupta has commendable operating skills which are par excellence. She is adept with modern facilities and techniques like phacoemulsification and femto laser-assisted cataract surgery. Her work is trusted beyond uncertainties all over Delhi. Also the cataract surgery cost is most reliable and worthy of the standard care that the facility provides.

FAQs

  • How can I achieve the best cataract surgery recovery?

Best cataract surgery recovery is possible by ensuring adequate rest to the eyes and protection against all sorts of irritants.

  • What Will Happen With My Eyes in the Future?

Cataract surgery restores your visual acuity to near accuracy by preventing and correcting blindness 

  • Can a Cataract Grow Back in the Synthetic Lens?

No. Cataract cannot develop on synthetic lenses as it is inorganic in nature compared to organic human tissue.

  • Why is my vision still blurry after cataract surgery?

Blurred vision after cataract surgery could be due to the eye taking its adapting time to the new intraocular lens or due to leakage in the retina from surrounding blood vessels. The vision becomes clear in a matter of a few days or 2-3 weeks.

  • Does cataract surgery involve incision?

Advanced cataract surgeries involve a small incision of 2.2 mm, which heals in a matter of hours.

Managing glasses or contact lenses everyday is a big hassle for most of us. But what if you do not need them anymore? Yes, it is very well possible by one of the most popular eye surgeries nowadays called LASIK (Laser-assisted in situ Keratomileusis) eye surgery. It is a procedure where the cornea is reshaped to restore normal vision. LASIK eye surgery gives tremendous outcomes when performed under the right hands and with the right technology.

1. How does LASIK surgery improve and restore your vision?

 LASIK eye surgery is done to correct refractive errors like Myopia, Hypermetropia, or Astigmatism, where the light is not correctly directed towards the retina which results in blurred vision.  In this surgery, a cutting laser very precisely changes the shape of the cornea (dome-shaped tissue in front of the eye.) resulting in bending light correctly onto the retina, thus restoring and improving your vision even without glasses /contact lenses. It reaps several benefits like:

  • It corrects your vision drastically.
  • It is a completely painless procedure.
  • Immediate results are achieved and normal activities can be resumed from the very next day, of course with some precautions.
  • It is cost-effective in the long run, as it reduces the use of eyewear and visit to ophthalmologists to a great extent.
  • It will improve your self-confidence and make you feel more active and comfortable.
  • You can engage in different sports activities without worrying about knocking off glasses.
  • Allergies by contact lenses like itching or watery eyes can be avoided by LASIK eye surgery.
  • Even if vision changes with age later, the doctor can adjust it.

2. Who is an Ideal Candidate for LASIK surgery?

Are you wondering if you can get the LASIK eye surgery done? Some keys which help you know if you are a good candidate are:

  • If you are an adult and over 18 years of age: As the eyesight keeps on changing until you are an adult.
  • If your eye power has been stabilized: stable eyesight is essential before having the surgery, else your vision might change post-surgery. Usually, doctors recommend that the eyesight need to be stable at least 6 months before the surgery.
  • If you have overall good health: Certain diseases like diabetes, some autoimmune diseases like arthritis, or eye diseases like glaucoma, cataracts, or dry eyes.
  • If you do not have very high power: LASIK eye surgery can correct power up to a certain limit,so very high power may not be corrected by this.
  • If you have a normal cornea: Since the cornea needs to be reshaped, it should be normal and of adequate thickness, else it can get weaken during reshaping.
  • Have clarity about the risks associated and have realistic expectations.
  • The Cost aspect is clear.

 A detailed and thorough doctor consultation, examination, and assessment are very important to decide on your surgery.

3. What does LASIK Surgery involve?

The LASIK surgery procedure basically involves two steps:

  • Making a flap on the cornea by an instrument.
  • Reshaping of the cornea with an excimer laser by removing tissue from the middle layer.

Usually takes around 15-20 minutes, but laser usage is just for a few seconds. Steps of the procedure involve:

  • Anesthetic drops are put to numb your eyes.
  • After you are relaxed and comfortable, and eyelid retractor is used to keep your eyelids open and the flap-making instrument is kept in position.
  • The doctor will ask you to look at the fixation light and will electronically activate the precision instrument, which will cut a corneal flap, revealing the middle layer of the cornea.
  • Then the cornea is reshaped by an excimer laser depending upon what error needs to be corrected.
  • After reshaping, the corneal flap is repositioned, and held in place by natural forces, until healing is complete.

LASIK eye surgery has an extremely quick recovery. Always follow your doctor’s instructions and be very regular with your follow-up visits to improve your vision.

4. Is LASIK eye surgery painful?

Fortunately, the LASIK surgery is not at all painful. The numbing solution dropped in your eyes helps to make your procedure completely painless and comfortable. Sometimes you may feel slight itching, burning, or watery eyes post-surgery, but this will resolve within a day or two.

5. What are the risks associated with LASIK surgery?

Although it is a very safe procedure, like all other surgeries, some risks with LASIK eye surgery may still be there:

  • Dry Eyes: There may be a temporary reduction in the formation of tears which may lead to dryness of the eyes. Lubricating drops are recommended.
  • Under corrections: Removal of lesser tissues may not result in clear vision and might require another surgery (Enhancement). 
  • Over Corrections: removal of excess tissues results in blurred vision and is difficult to correct, but it is rare.
  • Double vision, halos, and glare: Night vision may be compromised; glare, halos, and double vision may result around bright lights. Usually, this resolves within a few weeks.
  • Problems with the flap: Complications of infection and excess tears may occur and the outer layer of the cornea may abnormally grow under the flap.
  • Astigmatism: This may be caused by uneven tissue removal requiring additional surgery, spectacles, or contact lenses.
  • Regression: Your vision problem may relapse some years post-surgery, although it is not very common.
  • Loss of vision: This is a very rare complication

6. How much does LASIK eye surgery cost?

To most of us, LASIK surgery cost seems to be a steep one, but considering the cost to benefits ratio and the advantages, in the long run, it will come out to be affordable. LASIK eye surgery will reduce your ophthalmologist’s visit fees drastically and the cost of glasses and lenses will be nil for the rest of your life. Nevertheless, the cost of LASIK surgery will vary depending upon your condition of eyes, type of procedure, surgeon’s experience and qualifications, type of equipment used, etc.
