LASIK (LASER ASSISTED IN SITU KERATOMILEUSIS)

LASIK is a procedure used to correct nearsightedness, farsightedness, and astigmatism.The procedure is done under topical anesthesia. Anesthetic eye drops are administered to numb the eye before the surgery begins. With LASIK, the cornea is reshaped under a flap, thus changing the way the light entering your eye is focused. LASIK is able to correct to correct refractive errors from low to high. LASIK offers the advantage of quicker visual recovery, because it is done under a flap. The flap is then deflected back to expose the underlying corneal tissue. Then, using the excimer laser, a precise amount of tissue is removed to correct your specific refractive error. The laser, a cool laser, removes less than 1/1000 of a millimeter of tissue, less than the thickness of a human hair. For nearsighted individuals, tissue is removed from the central cornea, thus have the effect of flattening the cornea. For farsighted individuals, tissue is removed from the peripheral cornea, thus having the effect of steepening the cornea. The corneal flap is then replaced and precisely aligned to its' original position. Because of the natural bonding process that occurs in the cornea, sutures are not required.Vision is better immediately after surgery and continues to improve the next week. The entire procedure usually takes about 10 to 15 minutes per eye. Visit the FDA's site on LASIK to learn more about this procedure.

The cornea and lens combine to focus visual images on the back of the eye. When the overall shape of the eye is incorrect or when the curvature of the cornea is incorrect, the visual images are not in focus. The cornea accounts for approximately 2/3 of the focusing power of the eye. By surgically changing the corneal curvature, most or all of the blur can be eliminated.

Laser In Situ Keratomileusis (LASIK) and Photo-Refractive Keratectomy (LASIK) are two surgical techniques which utilize lasers to reshape or change the curvature of the cornea.

LASIK had its origins a little over a decade ago and was originally developed to treat patients who had very poor vision due to corneal disease. It has now evolved into a successful technique for correcting refractive errors. The current procedure, done on an outpatient basis, involves both the use of conventional and laser surgery to correct nearsightedness, farsightedness and astigmatism.

In performing LASIK, eye drop anesthetic is used to numb the eye. The surgeon then uses a special instrument to create a thin corneal flap. The laser, computer programmed to the patients prescription, is positioned over the eye. The laser changes the shape of the cornea to the patients prescription. The eye is then positioned under the excimer laser which has been computer programmed to remove microscopic amounts of the internal corneal tissue. Removal of the tissue changes the curvature of the cornea. The corneal tissue has extraordinary natural bonding qualities that allow effective healing without the use of stitches.

Since only local anesthetic is used, patients remain awake during the procedure. The entire procedure takes only a few minutes. Improved vision is often possible on the day following the surgery. Eye drops and night protection are necessary for designated periods of time.
