The PRK procedure begins with applying numbing eye drops to ensure patient comfort. The surgeon then gently removes the thin outer layer of the cornea, known as the epithelium, using a specialized instrument. Once the epithelium is removed, an excimer laser is employed to reshape the underlying corneal tissue, correcting the refractive error that causes vision problems. After the cornea has been reshaped, the treated area is covered with a special contact lens to protect the eye and aid in the healing process. Over the next few days, the epithelium regenerates, and vision gradually improves as the eye heals. Patients typically experience a noticeable enhancement in vision within a week, with continued improvement over the following weeks. PRK offers a reliable and effective solution for those seeking to improve their vision without a corneal flap.
