Utilizing the accuracy and precision of the excimer laser, LASIK changes the shape of the cornea to improve the way light is focused or "refracted" by the eye. First, a thin layer of the cornea, or corneal flap, is lifted up with an instrument called a microkeratome. Then, in less than 60 seconds, ultraviolet light pulses from the excimer laser reshape the cornea with accuracy up to 0.25 microns. By adjusting the pattern of the laser beam, it is possible to treat nearsightedness, farsightedness and astigmatism. After the underlying tissue has been reshaped, the flap is replaced in its original position. Healing is rapid and does not require stitches. LASIK is performed as an outpatient procedure in the comfort and convenience of our excimer surgical suite with the entire procedure taking less than 20 minutes for both eyes.
LASIK is performed using "eye drop" or topical anesthesia. Most patients report a slight, postoperative scratchiness that can be alleviated with lubricating drops. Many patients see a dramatic improvement in their vision within the first day, and most patients return to their normal activities, such as work and driving, the following day.

HOW IT WORKS

To treat nearsightedness, the cornea must be made flatter. This is accomplished by removing tissue from the center of the cornea.

To treat farsightedness, the central cornea must be made steeper. This is accomplished by directing the laser beam to remove tissue from around this area.

To treat astigmatism, the cornea must be made more spherical. By changing the pattern of the beam, tissue is removed in one direction more than the other.

MYOPIA
(Nearsightedness)
Myopia or nearsightedness occurswhen light rays are focused in front of the retina instead of directly on the retina.
ASTIGMATISM
Regular astigmatism occurs when light rays are focused at more than one point on the retina.
HYPEROPIA
(Farsightedness)
Hyperopia or farsightedness occurswhen light rays are focused behind, rather than on, the retina.
LASIK
(Laser in-Situ Keratomileusis)
The excimer laser removes microscopic layers of corneal tissue to change its shape, allowing light rays to focus more directly on the retina.
