LASIK (laser assisted in-situ keratomileusis) is the most common laser vision correction procedure performed today and can correct a wide range of conditions, including nearsightedness, farsightedness, and astigmatism. Using a highly accurate, cold beam excimer laser, the LASIK surgeon reshapes the cornea (the clear window on the front of the eye) to focus light rays directly on the retina.
During the LASIK surgery, a thin corneal flap is created using an instrument called a microkeratome. The corneal flap is gently folded back, and the excimer laser uses pulses of invisible ultraviolet light to gently reshape the internal tissue of the cornea. Each pulse of the laser removes only a minute amount of corneal tissue - about 1/500th of the thickness of a human hair. Depending on which is applicable, the laser is either guided by the WavePrint map created specifically for your eye or by the surgeon's skilled adjustment of the laser. The surgeon has full control of the laser and can turn it off at any time.
Once the cornea is reshaped, the corneal flap is replaced in its original position where it adheres quickly and seals itself without the need for stitches. The surgery only takes about five minutes per eye, and there is very little discomfort, either during the surgery or after. Typically, by the day after surgery, LASIK patients see well enough to drive and return to work. |
