Although LASIK is the most popular form of laser vision correction, some patients may be better candidates for Photorefractive Keratectomy (PRK). PRK is a laser surgery procedure that is very much like LASIK. In both LASIK and PRK, the goal is to reshape the cornea to the desired target, thusly reducing or eliminating the need for contacts and glasses.

How does LASIK and PRK  differ?

LASIK is a two-step process, the first step is to create a protective flap, and step two is to reshape the cornea with the cool-beam of the excimer laser.

In PRK, Dr. Gladsden will not create a corneal flap. He’ll begin by removing the protective cells on the surface called epithelium cells. Next, he’ll use the cool beam of the excimer laser to reshape the eye in the same manner as LASIK.

LASIK and PRK usually have the same result. However, with PRK, patients will have a slightly longer recovery time. With LASIK, patients generally see very well the day after their procedure. With PRK, the same visual results can take 3-7 days.


Some patients may not be good candidates for LASIK due to corneal thickness, problems with the surface of the cornea or dry eye. Some patients may have a lifestyle that requires PRK. Some instances may include military special ops, professional boxers or pilots.
