Refractive surgery is a blanket term encompassing a range of surgical modalities whose goal is to improve the refractive state of the eye and consequently reduce or eliminate dependence on eyeglasses or contact lenses.
Recent years have seen huge advances in this field. Most types of vision correction surgery reshape your cornea, the clear front part of your eye. That lets light travel through it and focus properly on the back of your eye, or retina. Other procedures replace your eye’s natural lens.
Refractive surgeries that involve corneal reshaping yield more than 90 percent success rate. With PRK surgery, in particular, up to 95 percent of people achieved 20/20 vision without corrective lenses.
