Your Ultimate Intraocular Lens Guide

Cataract surgery is a vision correction procedure. However, it does not give you a perfect vision in many cases. To achieve that, patients had to wear glasses or contact lenses after the treatment. But due to the advancements in the ophthalmic field, you can now avoid that extra fuss. 

The procedure of cataract surgery now includes implanting a new vision correction lens into each of your eyes. Lenses of different types and effects are available in the market from which you can choose. The availability of multiple options allows you to resolve your vision issues along with cataracts. 

We understand that too many options might also mean the stress of determining the best type for you. This is why we have brought together a guide for you to understand why these lenses are needed, what types of lenses are available, and how to choose the right type for yourself. 

Why Do You Need Lens After Cataract Surgery

A cataract is caused by the clumping together and accumulation of the proteins in your eye lens. This causes your vision to turn foggy and blurred. Many people also experience a halo effect and light sensitivity. The doctor removes these clumped-up proteins during the surgery, which naturally improves your vision. 

However, cataract is often observed in people around or above 40 years of age. During this time, a large part of the population also already suffers from vision defects like myopia, hypermetropia, or both. 

So even if you get cataract surgery, you might not get normal clear vision. To deal with this, a lens implant is coupled with a cataract surgical procedure

This way, your cataract and vision defect will be addressed with a single surgery. 

What Is An Intraocular Lens?

A lens is a flexible, clear, and curved structure lying right behind your iris, the brown part of the eyes. It works to focus the light rays to form a clear image. 

An intraocular lens can be considered an artificial version of your natural lens. It has a similar structure and performs the same function. These lenses can be customized to address your defects accurately

There are mainly two types of visual defects. The first is spherical, which is caused due to abnormalities or defects in your natural lens. The other is cylindrical, caused due to dissymmetry of the optical curvature. 

Different lenses are designed for each of these and other common issues. At Dr. Deepa Gupta’s Clinic, the doctor implants this lens during cataract surgery. The use of these lenses gives permanent results. 

What Are The Different  Types Of Intraocular Lens?

The different types of intraocular lenses have distinct features to focus on different visual defects. Hence, there is a high chance that you will find the one type that addresses your concerns. 

  1. Monofocal Lens

As the name suggests, a monofocal lens allows your eyes to focus on a single distance range. You can choose whether you want to see the nearby objects or distant objects without the help of prescription glasses or contact lenses. This lens deals with spherical vision defects. 

If you have either myopia or hypermetropia, the choice would be easy. However, while deciding, consider the fact that the lens would have a permanent effect. 

Usually, the doctor advises getting the lens with distance vision as that is used the most. However, if you are an artist or read very often, you might prefer getting a near-sighted lens.

  1. Multifocal Lens

If having to choose between near and distant vision does not sound appealing to you, a multifocal lens might catch your attention. It also addresses spherical vision defects. However, this lens can allow you to focus on near and distant objects

The power of the lens can be customized as needed. This could help you completely get rid of prescription glasses and contact lenses. 

Note that this lens has some downsides, including glare and decreased contrast sensitivity. 

  1. Toric Lens

A toric lens deals with spherical as well as cylindrical defects. As the only lens that corrects cylindrical defects, it is best for people with astigmatism because the condition is caused by a deviation from the normal spherical curvature of the eyes. 

The Toric lens works on moderate to high levels of astigmatism. However, it also has specific vision ranges. 

  1. Monovision

If none of the above lenses seem to work for you, this creative way definitely would! In monovision, the two eyes are implanted with two different lenses. Suppose the doctor implants one eye with a monofocal lens with near vision and the other eye with a monofocal lens with distant vision. This would allow you to see clearly in both visual ranges.

Which Lens Is Best For You?

The best lens for you depends on the type of visual defect you have. For instance, a toric lens is the best option for people with astigmatism. Monovision could be a smart way to address the issue if you have both myopia and hypermetropia. 

Also, note that you might need to consider your budget while choosing. The type of lens you go for might affect the final cost of cataract surgery

It is best to talk to your doctor about the matter. At Dr. Deepa Gupta’s Clinic, you can book an appointment with expert doctors. They would consider your vision status and suggest you the best options. You will also know if using a particular lens could have any side effects. 

As the results are permanent, thorough consultation and consideration are necessary

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.

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