Experience Better Vision With LASIK

By Alan C. Egge, MD

LASIK is an acronym for Laser In-situ Keratomileusis, which refers to the use of laser technology to reshape the cornea to correct a wide range of nearsightedness, farsightedness, and astigmatism. This surgical procedure combines the use of the microkeratome, which creates a partial flap in the cornea and the precision of the excimer laser which removes a thin layer of tissue from the cornea.

LASIK has been performed internationally for over 10 years. It was first performed in the U.S. in clinical trials in 1989. However, ophthalmologists have been reshaping the cornea for over 50 years, and using the excimer laser since the 1980’s.

LASIK is performed as an outpatient procedure. The actual surgery usually lasts less than 15 minutes, with most patients experiencing an improvement in their vision within the first few days of the procedure, some within hours of their treatment.

The Procedure

The eye is numbed with anesthetic eye drops. Then a microkeratome creates a partial flap in the cornea. The hinged flap is then folded back exposing the middle part of the cornea.

The computer-controlled excimer laser, having been preprogrammed for the patient’s correction, is applied to the exposed corneal surface to remove a microthin layer of tissue.

In the final step, the flap is folded back into its original position. The treated area is completely covered by the flap.

Following the procedure, you will be given eye drops, protective sunglasses, and eye shields to help your eyes heal. By the next morning, your vision will be greatly improved. Your vision maybe slightly blurry for a few days, but most patients return to work within 48 hours.
