Understanding LASIK

What is LASIK?

If you are one of the 70 million people currently diagnosed with nearsightedness (myopia), farsightedness (hyperopia), astigmatism, or a combination of these conditions, you probably have heard of LASIK (Laser In-situ Keratomileusis.)  This revolutionary technique uses Excimer laser technology to precisely reshape the cornea, effectively treating vision problems.  As a result of LASIK, many patients have found their vision restored up to, or better than 20/20.

How LASIK works

LASIK uses either a sophisticated instrument called a microkeratome or a precise laser, the Intralase, to create a flap from the top layer of the cornea.  The flap is gently folded back, then the laser sculpts the midcornea to reshape the eye and reduce or eliminate the need for glasses and contact lenses.  LASIK utilizes the Excimer laser to reshape the cornea under a protective layer of tissue.  The Excimer laser uses cool ultra violet light to treat the cornea.  It does not treat beyond the cornea and is extremely precise. The flap is then repositioned and the procedure is complete.  Since the surface cells of your eyes heal more rapidly than any other body part, recovery occurs quickly and naturally.  Visual recovery occurs usually within 24 hours and there is minimal discomfort after surgery.
