One of the safest and most commonly performed surgical procedures in the world, LASIK has allowed millions of people to reduce or eliminate their dependence on glasses and contact lenses. LASIK, or Laser-Assisted In-Situ Keratomileusis, is a quick, virtually painless procedure in which a laser is used to reshape the cornea, the transparent top layer of the eye. Because the cornea is a powerful part of the eye’s focusing mechanism, flaws in its shape result in such common vision disorders as nearsightedness, farsightedness, and astigmatism. By restoring the cornea to its proper, spherical shape, our surgeon is able to improve the eye’s focusing power and restore vision, often to 20/20 or better.

Laser-Assisted In-Situ Keratomileusis (LASIK) is an FDA-approved surgical procedure intended to reduce dependency on eyeglasses or contact lenses. It is performed on nearly 1 million patients each year to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism by permanently altering the shape of the cornea, the eye's thin, transparent covering. This reshaping of the cornea increases the eye’s focusing power and improves vision.
During LASIK surgery, a thin incision is made to form a flap in the surface of the cornea. The flap is folded back to reveal the cornea’s midsection, called the stroma. Next, an excimer laser is used to remove a thin layer of the stroma. Lastly, the flap is repositioned. As with any surgical procedure, there are risks involved with LASIK. Side effects may include excessively dry eyes, corneal scarring, corneal edema, persistent eye pain or discomfort, glare and halos in the line of vision, and a decreased ability to see well at night or in fog. However, most of these subside as healing progresses after surgery. Many of these complications can be avoided through a newer variation of the procedure called epi-LASIK.
LASIK to Treat Hyperopia
Hyperopia occurs when light rays focus behind the retina rather than on it. This condition, which allows one to see distant objects much more clearly than objects that are close, is generally caused by a “short eye” or a cornea that is too flat. In the latter case, hyperopia can usually be treated with LASIK, which will increase the curvature of the cornea in order to allow light rays to focus properly.

LASIK to Treat Astigmatism
In a normal, healthy eye, the cornea is round. In an astigmatic eye, it is closer to the shape of a football, which prevents the eye from focusing light in just one place on the cornea; instead, light rays focus at several points, blurring near, middle, and distant vision.
LASIK can correct irregular curvature and improve the eye’s focusing ability. It can ultimately improve near, middle, and distant vision.
