New Lasic

Lasik is a new procedure that borrows technology from laser keratotomy and radial keratotomy to correct near sightedness and astigmatism. To correct near sightedness, doctors try to change the way light is refracted through the eye.

The cornea is like the clear windshield of the eye and refracts or bends light as it enters into the eye. The purpose of the surgery is to reduce the patient’s dependency on glasses or contact lenses. In the lasik procedure the surgeon lifts the cornea from the side producing a flap. This flap is rolled back to expose the inner layer of the cornea. With the flap folded back, the doctor now makes the refractive correction on the inner layer of the cornea. This is done with an Exma laser. The Exma laser allows for an unparalleled degree of precision. Each pulse of the laser can remove 1/39 millionth of an inch of tissue on 1/12 billionth of a second. When treatment is complete the flap is repositioned into its original position. The flap heals completely a few days after the procedure. Because little of the epithelium is disturbed the patients report a high comfort level after the procedure.
