Photorefractive Keratectomy (PRK) is a type of laser eye surgery used to correct myopia (near-sightedness), hyperopia (farsightedness), and astigmatism. It works by reshaping the cornea using an excimer laser, allowing light to properly focus on the retina, leading to improved vision.
The Photorefractive Keratectomy (PRK) Procedure
The procedure involves numbing the eyes with topical anesthesia, removing the corneal epithelium, and reshaping the cornea with an excimer laser. A bandage contact lens is then placed over the eye to protect it and promote healing. The procedure takes 15-30 minutes per eye and is performed on an outpatient basis.
