PRK (Photorefractive Keratectomy): How this works.

PRK can correct near and farsightedness and astigmatism using the cool Excimer laser light to remove the top layer of corneal tissue. The rays of light are precisely computer guided and actually vaporize the anterior layers of the cornea. The cornea is reshaped to your specific prescription. Like LASIK, mild numbing eye drops are used. After surgery some eye sensitivity is typically present for about 24 to 48 hours. PRK usually takes about ten (10) minutes to perform.
