Operation - Photorefractive Keratectomy (PRK) is a laser surgery that corrects vision by reshaping the cornea after outer epithelial layer is gently removed. It has a success rate over 90% and recovery varies with initial healing in a few days and full visual stabilization over several weeks to a few months.
Average Patient Treated - Typically individuals seeking permanent vision correction who are not ideal candidates for LASIK surgery, often because they have thin corneas, dry eye, irregular corneal shape, or high-risk lifestyles (e.g., contact sports or military service). It is also a common procedure for patients with mild to moderate myopia (nearsightedness), hyperopia (farsightedness), or astigmatism.
