Understanding Keratoconus Treatment: Exploring the Stages and Innovative Approaches – PRK vs. Laser

October 16, 2023 0

Keratoconus is a progressive eye disorder that affects the cornea, causing it to become thin and irregularly shaped. This condition can lead to significant visual impairment and discomfort for those affected. Fortunately, there are various treatment options available to manage keratoconus, and two of the most common approaches are Photorefractive Keratectomy (PRK) and laser-assisted procedures. In this blog, we will delve into the stages of keratoconus and explore the differences between PRK and other laser-based treatments.

Understanding Keratoconus

Before we dive into the treatment options, it’s essential to understand keratoconus and its stages. Keratoconus typically progresses through several stages:

  1. Early Stage:

In the early stages, patients may not even be aware of the condition as their vision remains relatively stable. However, subtle changes in vision, such as astigmatism and nearsightedness, may be present.

  1. Moderate Stage: 

As keratoconus advances, patients may experience blurred and distorted vision. Contact lenses or glasses may still be effective in correcting vision at this stage.

  1. Advanced Stage: 

In the advanced stage, vision worsens significantly, and traditional corrective measures may become less effective. Patients may experience increased sensitivity to light, halos, and glare.

  1. Severe Stage:

The cornea becomes extremely thin and steep in the severe stage, leading to substantial visual impairment. Standard glasses and contact lenses often do not provide adequate vision correction.

PRK (Photorefractive Keratectomy)

PRK is a type of laser eye surgery that is sometimes used to treat keratoconus, particularly in its early to moderate stages. Here’s how PRK works:

  1. Preparation:

Before the surgery, the corneal epithelium (the outermost layer of the cornea) is removed.

  1. Laser Reshaping:

A laser is then used to reshape the cornea to improve its curvature and correct vision problems.

  1. Healing:

After the procedure, the epithelium naturally regenerates over a few days to weeks.

PRK is considered a safer option for keratoconus patients than LASIK (Laser-Assisted In Situ Keratomileusis) because it doesn’t involve creating a flap in the cornea, which can be risky for weakened corneas.

Laser-Assisted Procedures

Several laser-assisted procedures can be beneficial for keratoconus patients:

  1. Corneal Collagen Cross-Linking (CXL): 

CXL is a non-invasive procedure that strengthens the cornea by increasing collagen bonds. It can help halt the progression of keratoconus.

  1. Intracorneal Ring Segments (ICRS): 

ICRS, also known as corneal implants, are small plastic rings inserted into the cornea to reshape it, improving vision for some keratoconus patients.

  1. Topography-Guided LASIK:

In cases where keratoconus is stable, topography-guided LASIK may be considered to correct vision.

  1. Implantable Collamer Lenses (ICLs):

ICLs are an option for advanced keratoconus. These lenses are implanted inside the eye to provide vision correction.

Choosing the Right Treatment

The choice between PRK and other laser-assisted procedures depends on the severity of keratoconus, the patient’s circumstances, and the recommendations of their eye care specialist. PRK is more suitable for early to moderate stages, while advanced cases may require a combination of treatments or alternative procedures like CXL or ICLs.


The cost of keratoconus treatment in Delhi, India, can vary depending on the specific treatment chosen, the severity of the condition, the medical facility, and the surgeon’s experience. Here is a general estimate of the cost range for keratoconus treatment options in Delhi:

  1. Photorefractive Keratectomy (PRK):

PRK surgery in Delhi typically costs between ₹40,000 to ₹60,000 per eye. This cost may include pre-operative and post-operative care.

  1. Corneal Collagen Cross-Linking (CXL):

The cost of CXL in Delhi can range from ₹20,000 to ₹40,000 per eye, although prices may vary depending on the facility and the type of CXL used.

  1. Intracorneal Ring Segments (ICRS): 

The cost of ICRS insertion in Delhi generally ranges from ₹40,000 to ₹80,000 per eye. The actual cost may depend on the type and number of rings used.

  1. Topography-Guided LASIK: 

The cost of topography-guided LASIK in Delhi can vary widely, ranging from ₹40,000 to ₹80,000 per eye or more, depending on the surgeon’s fees and the facility.

  1. Implantable Collamer Lenses (ICLs): 

ICLs are a more expensive option, and the cost in Delhi may range from ₹80,000 to ₹1,50,000 or more per eye. This typically includes the lens implant and the surgical procedure.

Additionally, it’s essential to inquire about any potential financing options or insurance coverage that may be available to help manage the expenses associated with keratoconus treatment in Delhi.


Keratoconus is a progressive eye condition that can significantly impact one’s quality of life. Understanding its stages and the available treatment options, such as PRK and other laser-assisted procedures, is important for making apprised decisions about managing the condition.

Consulting with an experienced eye specialist is the first step toward determining the most appropriate treatment plan for an individual’s unique needs and circumstances. With the right approach, many keratoconus patients can achieve improved vision and a better quality of life.


Dr. Deepa Gupta is a renowned ophthalmologist whose clinic in Gurgaon, Delhi, has earned a stellar reputation for its expertise in treating various eye conditions. One of the clinic’s major areas of specialization is Keratoconus treatment, a condition that affects the cornea and can lead to distorted vision.

Dr. Gupta’s clinic is at the forefront of offering cutting-edge solutions for individuals suffering from Keratoconus, providing hope and improved vision to countless patients.

Keratoconus is a progressive eye disorder characterized by the thinning and bulging of the cornea, leading to a distorted and irregularly shaped cornea. This condition can cause severe visual impairment, making it challenging for individuals to carry out their daily activities.

Dr. Deepa Gupta’s clinic is a beacon of hope for those afflicted by this condition, offering a range of advanced treatments to manage and correct Keratoconus.

One of the primary treatment options provided at Dr. Gupta’s clinic is Corneal Cross-Linking (CXL). This minimally invasive procedure involves applying a special solution to the cornea, followed by controlled exposure to ultraviolet light.

This process strengthens the collagen fibers in the cornea, halting the progression of Keratoconus. Corneal Cross-Linking has proven to be highly effective in stabilizing the cornea’s shape and preventing further deterioration, preserving and improving patients’ vision.

Another cutting-edge Keratoconus treatment offered at the clinic is Intracorneal Ring Segments (ICRS) insertion. These small, implantable rings are placed within the cornea to reshape it, reducing the distortion caused by Keratoconus. This procedure has the potential to significantly improve visual clarity and reduce the reliance on corrective lenses for patients.

For those whose Keratoconus has progressed to an advanced stage, Dr. Gupta’s clinic provides access to advanced surgical options such as corneal transplantation. This procedure involves replacing the damaged cornea with a healthy donor cornea and restoring vision in cases where other treatments may not be sufficient.
