Laser Eye Surgery Overview
Laser eye surgery—including the popular LASIK surgery—involves the modification of the cornea. By changing the shape of your cornea, the focusing power of the eye is improved and refractive errors such as near or farsightedness and astigmatism can be corrected.
During laser eye surgery, your surgeon cuts a flap in an area of the eye, leaving a hinge at one end. Once the flap is folded back, a laser changes the shape of the middle section of the cornea. The flap is returned to the original position and the procedure is finished. There are different specialized procedures that correct focal problems. The most common are LASIK and PRK.
