PRK
Reference only — not medical advice. See disclaimer.
Photorefractive Keratectomy (PRK) is a laser refractive eye surgery technique in which the outer epithelial layer of the cornea is removed and an excimer laser is applied directly to the corneal surface to reshape it and correct refractive errors, without the creation of a corneal flap. It is often recommended for patients with thin corneas or those at risk of flap complications from LASIK.
