The Risks Of Lasik Surgery

The 21st century is the golden age for surgical procedures, among them an increasingly popular method of corrective eye surgery known as LASIK. LASIK is an acronym for the surgery, which stands for Laser Assisted In Situ Keratomileusis. This procedure has become increasingly reliable, with unresolved complications reported in only 3 to 6 percent of patients. The risk of complications is still there, however, and can take several different forms.

The complications of LASIK surgery can include the following: Dry eyes, over or under correction, visual acuity fluctuation, halos or starbursts around light sources at night, light sensitivity, double vision, wrinkles in the flap, striation, decentered ablation, debris or growth under the flap, induced astigmatism. These complications are classified according to whether they arise in the preoperative procedures, the procedure itself, or after the operation either early on or later.

Each of the complications is unique unto itself, and it is important to remember that LASIK surgery is irreversible should nay of the complications occur. May of the complications such as halos and ghosts are not tested by standard eye tests, and need to be accounted for separately.

Over and under correction are the result of the surgeon incorrectly estimating the concentration that needs to be applied during the surgery. Many risks of LASIK surgery can also be increased by phenomena that may not have occurred to the patient, such as racial origin and environmental occurrences.

Improperly formed flaps can lead to an irregular surface and vision defects as the flap fails to properly adhere to the surface of the eye. This condition can be corrected with further surgery, although the costs will usually continue to accrue and sometimes a decrease in visual acuity. A flap that is too thick can also weaken the eye
