Photorefractive keratectomy - Wikipedia, the free encyclopedia  Photorefractive keratectomy (PRK) and Laser-Assisted Sub-Epithelial Keratectomy (LASEK) are laser eye surgery procedures intended to correct a person's vision, reducing dependency on glasses or contact lenses. The first LASEK procedure was performed at Massachusetts Eye and Ear Infirmary in 1996 by ophthalmologist, refractive surgeon, Dimitri Azar. [1] The procedure was later popularized by Camellin, who coined the term LASEK for laser epithelial keratomileusis.
