PRK (Photorefractive Keratectomy) is a laser eye surgery used to correct common refractive errors such as myopia (short-sightedness), hyperopia (long-sightedness), and astigmatism. Unlike LASIK, PRK does not create a corneal flap. Instead, the thin outer layer of the cornea is gently removed, and an excimer laser reshapes the corneal surface to improve how light focuses on the retina.
Who May Benefit From PRK?
PRK may be considered for people who are not suitable candidates for LASIK, including some patients with relatively thin corneas or certain corneal characteristics. A detailed eye examination is necessary to determine whether PRK eye surgery is appropriate.
PRK Procedure and Recovery
The procedure is performed using numbing eye drops and generally takes only a short time. A protective contact lens may be placed over the cornea while the surface heals. Vision can be blurry or uncomfortable during the first few days, and visual recovery is generally slower than after LASIK. Your ophthalmologist will provide specific instructions for medications, eye protection, and follow-up visits.
