PHOTOREFRACTIVE KERATECTOMY (PRK)

Photorefractive Keratectomy (PRK) is a laser vision correction procedure that reshapes the cornea to reduce dependence on eyeglasses or contact lenses. The surgeon uses an excimer laser to correct nearsightedness, farsightedness, and astigmatism. As a result, light focuses more accurately on the retina and vision becomes clearer.

WHAT PRK TREATS

PRK corrects refractive errors by changing the curvature of the cornea. Therefore, it improves how your eye bends incoming light. Eye doctors often recommend PRK for patients with thin corneas or surface irregularities. In addition, PRK avoids a corneal flap, so it can suit patients with higher eye trauma risk activities.

HOW THE PROCEDURE WORKS

First, the surgeon applies anesthetic eye drops to keep you comfortable. Next, the surgeon gently removes the thin surface layer of the cornea. Then, a computer-guided excimer laser reshapes the corneal tissue in seconds. Afterward, the surgeon places a protective contact lens to support healing. Consequently, the corneal surface grows back over several days.

RECOVERY AND VISUAL RESULTS

Vision improves gradually after PRK. During the first few days, you may notice mild discomfort, tearing, and light sensitivity. However, your prescribed medications help control these symptoms. Many patients regain functional vision within days, while sharper vision develops over weeks. Therefore, follow-up visits help your doctor track healing and protect your outcome.

SAFETY AND CLINICAL VALUE

PRK offers a strong safety record when your doctor performs proper screening and you follow aftercare instructions. Moreover, the flap-free approach removes certain flap-related risks. Modern laser platforms also support precise, predictable treatment. As a result, many patients achieve stable vision and improved daily function.
