What is PRK?
Photorefractive keratectomy (PRK) is a laser eye surgery that uses an excimer laser to remove microscopic corneal tissue and reshape the cornea. It corrects myopia, hyperopia, and astigmatism and reduces dependence on glasses or contact lenses.
No corneal flap — avoids flap-related complications.
Suitable for thin or irregular corneas not eligible for LASIK.
Preserves corneal strength, making it safer for some occupations and athletes.
Stable, long-term visual results with predictable outcomes.
Eliminates flap-dislocation risk during future trauma.
Effective for a wide range of refractive errors.
Myopia (nearsightedness): flattens the cornea to improve distance vision.
Hyperopia (farsightedness): steepens the cornea to improve near focus.
Astigmatism: smooths irregular corneal curvature for clearer vision.
Why Choose ASG for PRK
ASG pairs experienced refractive surgeons with advanced excimer lasers and detailed pre-op mapping to deliver safe, predictable PRK outcomes. Our thorough screening, personalised plans, and careful follow-up ensure a comfortable recovery and lasting visual improvement.

Clear Answers for Better Vision
What is PRK surgery?
PRK (Photorefractive Keratectomy) is a type of laser vision correction surgery used to treat nearsightedness, farsightedness, and astigmatism. Unlike LASIK, which creates a flap in the cornea, PRK removes the thin outer layer (epithelium) of the cornea before reshaping the surface with a laser.
How is PRK different from LASIK?
The main difference is the “Flap.” LASIK involves creating a flap in the corneal tissue, while PRK is a “surface-level” procedure with no flap. This makes PRK an excellent choice for individuals with thin corneas or those whose occupations/hobbies put them at risk of eye injury (like contact sports or military service).
Who is an ideal candidate for PRK at ASG Eye Hospital?
PRK is often recommended for:
Patients with thin corneas who were rejected for LASIK.
Individuals in the Army, Navy, or Police force (where flap-based surgeries may not be allowed).
Athletes involved in contact sports like boxing, MMA, or football.
People with chronic dry eye symptoms.
Why is PRK preferred for defense/military candidates?
Because PRK does not involve creating a permanent corneal flap, there is zero risk of “flap displacement” due to physical trauma. Many defense and aviation medical boards prefer or require PRK for vision correction for this reason.
Is the PRK procedure painful?
The surgery itself is painless as we use numbing eye drops. However, because the surface layer of the cornea needs to regrow, patients may experience some discomfort, watering, or a “gritty” sensation for 3 to 5 days after the procedure. At ASG, we provide specialized “Bandage Contact Lenses” to minimize this discomfort.
How long does it take to see clearly after PRK?
Recovery for PRK is slower than LASIK. Vision is usually blurry for the first 3–5 days as the surface layer heals. Significant improvement is noticed within 1–2 weeks, but your “best” vision may take 3–6 months to fully stabilize.
What is a "Bandage Contact Lens"?
Immediately after PRK surgery, our surgeon places a clear, non-powered contact lens over the eye. This acts as a protective shield while the epithelium (surface layer) regrows, significantly reducing pain and speeding up the healing process.
Are the results of PRK as good as LASIK?
Yes. Studies show that 6 months after surgery, the visual outcomes of PRK are identical to LASIK. The difference is only in the speed of recovery, not the quality of the final vision.
What are the risks of PRK surgery?
While PRK is very safe, potential risks include temporary light sensitivity, haze (cloudiness) during the healing phase, or a longer-than-usual healing time. Our surgeons at ASG use specialized medications during the procedure to prevent haze and ensure a smooth recovery.
Why should I choose ASG Eye Hospital for PRK?
ASG Eye Hospital uses advanced Ablation Profiles that minimize tissue loss and optimize visual quality. Our surgeons are experts in assessing whether PRK, LASIK, or SMILE is the safest option for your specific corneal thickness and lifestyle.
