Frequently Asked Questions (FAQ) :
1. How long does it take to recover from PRK surgery?
Most patients recover within 3-5 days, although full vision improvement may take a few weeks.
2. Is PRK painful?
No, PRK is performed under anesthetic eye drops, so there’s no pain during the procedure. Mild discomfort or irritation may be felt in the days following surgery.
3. What is the difference between PRK and LASIK?
PRK removes the corneal epithelium, while LASIK creates a corneal flap. PRK is preferred for patients with thinner corneas or those at risk for flap complications.
About PRK
PRK is a type of refractive surgery designed to improve vision by reshaping the cornea, allowing light to focus more precisely on the retina. Unlike LASIK, which involves creating a flap in the cornea, PRK removes the cornea’s outer layer (epithelium) and then uses an excimer laser to reshape the underlying tissue.
Causes for PRK Surgery
PRK is usually recommended for individuals who:
- Suffer from nearsightedness (myopia), farsightedness (hyperopia), or astigmatism.
- Have thin corneas and are not suitable candidates for LASIK.
- Prefer a no-flap laser eye surgery option.
Dr. Suraj Munjal offers personalized evaluations to determine if PRK is the right treatment based on your unique vision needs.
Types of PRK Surgery
PRK surgeries can vary slightly based on technology and technique:
- Standard PRK: Traditional PRK procedure where the epithelium is removed manually before laser treatment.
- TransPRK (Transepithelial PRK): A no-touch procedure where the laser removes the epithelium automatically, providing more comfort and precision.
- Customized PRK: Tailored to the individual’s eye shape and corneal condition using advanced mapping technologies.
Symptoms that Indicate PRK May Be Needed
If you are experiencing the following symptoms, you may benefit from a PRK evaluation:
- Blurry vision at different distances.
- Frequent need to change prescription glasses or contact lenses.
- Difficulty seeing objects clearly when driving or reading.
- Glare or halos around lights at night.
Diagnosis: How to Know If PRK is Right for You
Dr. Suraj Munjal performs a comprehensive eye exam to assess your vision and determine if PRK is the best choice. Diagnostic steps include:
- Corneal topography: Mapping the surface of the cornea to measure its shape and thickness.
- Vision acuity tests: Assessing how clearly you can see.
- Pupil size measurement: Evaluating how much your pupil changes in size under various lighting conditions.
- Dry eye testing: Ensuring your eyes produce enough tears to recover well post-surgery.
PRK Treatment Procedure
The PRK procedure is safe, effective, and typically takes 15-20 minutes per eye. Here’s what to expect:
- Anesthetic eye drops are applied to numb the eye.
- The outer layer of the cornea (epithelium) is gently removed.
- An excimer laser is used to reshape the cornea, correcting your vision.
- A protective contact lens is placed over the eye to promote healing.
Cost of PRK Treatment and Stay in India
The cost of PRK surgery varies based on individual requirements and the type of procedure (Standard, TransPRK, Customized). On average, the cost ranges between INR 40,000 to INR 80,000 per eye.
For international patients, India offers high-quality, affordable eye care. Dr. Suraj Munjal’s clinic provides support for medical tourism with services such as:
