PRK (Photorefractive Keratectomy) is a type of laser eye surgery that reshapes the cornea to correct vision problems such as nearsightedness, farsightedness, and astigmatism.
It was the first type of laser vision correction and remains a safe, effective, and proven alternative to LASIK, especially for patients who are not ideal LASIK candidates due to thin corneas or certain corneal irregularities.
How PRK Works
The surgeon gently removes the thin, outer surface layer of the cornea (epithelium).
A cool excimer laser is then used to reshape the corneal tissue underneath, improving how light focuses on the retina.
The epithelium naturally grows back within a few days.
There is no flap created in PRK, unlike LASIK — which makes PRK a better option for some patients.
Who Is a Good Candidate?
PRK may be suitable for people who:
Have thin corneas or irregular corneal shapes
Have dry eyes or are at higher risk of trauma (e.g., athletes, military personnel)
Are over 18 years old with a stable prescription for at least one year
Want to reduce or eliminate dependence on glasses or contact lenses
The Procedure
1. Anesthetic eye drops numb the eye — no injections or general anesthesia.
2. The surface cells (epithelium) are gently removed.
3. The laser reshapes the cornea in less than a minute per eye.
4. A soft bandage contact lens is placed to protect the eye during healing.
5. The entire procedure usually takes 10–15 minutes per eye.
Recovery and Healing
The surface cells take 3–5 days to regenerate.
Some mild discomfort, tearing, or light sensitivity is normal during this period.
Vision improves gradually over several days to weeks.
Most patients achieve stable, clear vision within 1–2 months.
Eye drops and medications help control healing and comfort.
Benefits of PRK
Excellent long-term vision results (comparable to LASIK)
No corneal flap — safer for thin or irregular corneas
Lower risk of certain flap-related complications
Ideal for active lifestyles or high-impact environments
Possible Risks or Side Effects
Temporary dry eyes or glare/halos at night during healing
Slightly longer visual recovery than LASIK
Rare risk of corneal haze (usually temporary and treatable)
