Now Playing: What Happens During PRK?
Video Text
PRK is an excellent laser procedure used to treat some of the same conditions that LASIK does. It is an excellent option for those patients whose corneas are too thin for the LASIK, or whose eyelids are too narrow for the microkeratome to be placed. Instead of making a flap in the cornea, PRK actually removes the top layer of the cornea, called the epithelium, and the laser is used to reshape the eye.
Because no flap is created, PRK does not have any possible flap complications. However, PRK does carry a higher risk of haze or scarring; and for patients who need a greater correction - sometimes original successful results can decrease over time. PRK also requires a longer recovery period, usually 7 to 10 days, and patients experience more discomfort during healing.
Your doctor may advise you that PRK is an option for you if LASIK cannot be performed.
