PRK, or photorefractive keratectomy, was the first laser vision procedure developed. This is a surface laser vision treatment, meaning that no corneal flap is created as in LASIK. Treating on the surface of the cornea is better for patients with thin or scarred corneas.
What is PRK?
PRK is a procedure that corrects vision by reshaping the cornea. This procedure can be used to correct nearsightedness, farsightedness and astigmatism. First, anesthetic eye drops will be used to numb the eyes, no injections or needles will be used. Next, Dr. Beers or Dr. Liu will remove the epithelium – a thin layer of protective skin that covers the cornea. Then, computer controlled pulses of laser light are delivered to reshape the cornea. The laser will be programmed with the information gathered during your preoperative exam. The laser treatment is completed within a minute or two, depending on your specific correction needed.
At Peninsula Laser Eye Medical Group, we prefer a more advanced form of PRK, called LASEK. Please visit this page for more information about LASEK.
