PRK is a minimally invasive laser surgical procedure which reshapes the cornea.
Like LASIK surgery, PRK corrects refractive errors such as nearsightedness, farsightedness and astigmatism. Different from LASIK, during PRK the corneal skin (epithelium) is polished off before the laser treatment. In LASIK surgery, a small flap is cut in the epithelium. The healing process takes longer after PRK. Sometimes, PRK is the best procedure for specific patients. Your pre-operative evaluation will determine which procedure is best for you.
