PRK ("surface ablation")
If your corneas are too thin to create the corneal flap needed for LASIK, PRK may be an option for you. PRK is often called "bladeless LASIK" or "surface ablation" because PRK applies the laser vision correction treatment to the top surface of the cornea, while LASIK applies the laser in the center of the cornea after the creation and lifting of a portion of the cornea. It is considered the safer procedure for patients who have an active lifestyle or work in professions with debris in the air. Because PRK does not require the creation of a corneal flap, all potential flap complications are eliminated.
PRK can be used to treat myopia (near-sightedness), hyperopia (farsightedness) and astigmatism. In PRK, the epithelium, or surface corneal cells, are first gently removed. The laser treatment is then applied to the eye. Afterwards a clear contact lens is placed on the eye by the surgeon to act like a bandage during the healing process. The patient wears the contact lens for the first 3-4 days after surgery or until the epithelium layer has completely regenerated. The lens will be removed by the doctor at a post-operative visit.
