Laser Assisted In Situ Keratomileusis, commonly referred to as LASIK, is a medical eye procedure that permanently changes the shape of one’s cornea (the transparent, front part of the eye). LASIK is an outpatient laser refractive surgery designed to reduce a patient’s dependency on glasses or contact lenses. Since the first excimer laser was FDA approved in 1998, hundreds of thousands of patients have undergone LASIK procedures. LASIK is performed by certified ophthalmologists who are medical doctors specializing in the treatment of eye diseases and preventative care.

According to the American Society of Cataract and Refractive Surgery, LASIK is the most commonly performed type of laser surgery in the United States, and is a generally safe and effective treatment for a wide range of common vision problems. LASIK treats such conditions as myopia, (nearsightedness); hyperopia, (farsightedness), and astigmatism (irregular shape of the cornea).

During the initial consultation, your ophthalmologist will perform a variety of special medical eye tests to determine whether you’re an ideal candidate for LASIK.

The LASIK procedure takes about 15 minutes and includes several steps. First, the surgeon numbs your eye with topical anesthesia drops. No needles are used. Then, a special knife (microkeratome) is used to raise the thin layer of the cornea to create a flap. The flap is carefully protected while the surgeon ensures proper laser alignment. The excimer laser is computer-controlled and removes tissue beneath the flap. In less than 60 seconds, ultraviolet light and high-energy pulses reshape the cornea with an accuracy of up to 1/4000 of a millimeter. Finally, the flap is returned to its original position. Your doctor observes the eye for several minutes to make sure proper bonding occurs. Healing begins immediately, and no stitches are required. A shield is placed over your eye to protect the flap.

What are the Risks? In a recent report the American Academy of Ophthalmology stated that for low to moderate nearsightedness LASIK has been effective and predictable, and shows very good to excellent uncorrected visual acuity. However, as with any surgery, there can be risks associated with LASIK. Risks and possible complications include over, or under correction; eye infection; loss of best visual acuity; corneal scarring; decreases in “crisp” vision; flap problems; and trouble with night driving.

In addition to the risks, it’s important to realize side effects are rare, but they can also occur. Usually, side effects disappear within two months. You could notice slight discomfort, blurry vision, dryness, scratchy sensations, glare or haloes and light sensitivity.

Since LASIK is a relatively new procedure long-term complications remain unknown. However, recent technological advances, such as enhanced micorkeratomes and improved excimer laser tracking systems have significantly reduced the number of reported surgical problems.

What are the Benefits? The Eye Surgery Education Council says people choose LASIK for a variety of personal reasons. LASIK allows patients to more freely pursue hobbies, sports activities (such as swimming, jogging and exercising) and explore career options – without dependency on corrective lenses. Whether you’re an athlete, frequent traveler or a professional with a hectic schedule, LASIK can eliminate the long-term costs and daily hassles of life with corrective lenses.
