PRK is a laser vision correction procedure, much like LASIK, that reshapes the front of the eye. PRK is often the preferred therapy for patients with thin corneas, or who do not want a flap created, which is the technique used in LASIK surgery. A PRK procedure is very similar to LASIK and can produce the same results, though the recovery time is usually a little bit longer.
The PRK is a laser procedure that reshapes the cornea of the front of the eye to eliminate refractive errors. Unlike Lasik where the procedure is performed under a flap, PRK is performed on the surface and the surface heals.
Candidates for PRK are very similar to Lasik. Some patients request PRK because they don't like the idea of a flap. Some patients can't have Lasik because the cornea may be too thin so those patients typically are better candidates for PRK. The actual procedure is about 10 minutes per eye, so maybe 20 minutes for both eyes to be done. The recovery is a little bit longer because you have to wait for the surface to heal. The results are very, very high satisfaction. It's similar to... It's almost exactly the same as Lasik surgery as well, it just takes a little longer to get there.
