LASIK stands for “laser in situ keratomileusis.” The word “keratomileusis” comes from the Greek words “kerato,” meaning cornea, and “mileusis,” meaning shaping. It is a type of refractive surgery that corrects vision problems caused by an irregular shape of the cornea, the clear, round dome at the front of the eye. For many people, LASIK is the best way to reduce or eliminate their dependence on glasses or contact lenses. It also provides freedom from the inconveniences of a daily contact lens care routine.
