LASIK improves vision safely and precisely by reshaping the cornea to correct nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. Vision improves within minutes, and most patients eventually enjoy 20/20 vision or better after treatment.
Photorefractive Keratectomy (PRK)
PRK or photorefractive keratectomy is one of the safest and most time-tested laser vision correction procedures available. Before LASIK, PRK was the most common refractive surgery procedure. Like LASIK, it reshapes the cornea to improve vision. PRK is now used mainly for patients with large pupils or thin corneas.
