What are the complications associated with LASIK?
LASIK surgery is quite safe. The risks or complications following LASIK appears to be very few. Some of the complications are: • Flap complications: Very rarely, the corneal flap might be very thin and may have a hole. In such cases, the final surface of the cornea might be irregular resulting in poor vision. If this occurs, the procedure is stopped and the flap is allowed to heal first. The LASIK can then be attempted again after 6-12 later. Sometimes, the flap may not stick down tightly after the surgery, or become infected. Cells from the outer surface of the cornea might grow under the flap causing the cornea to become cloudy and irregular. An extremely rare but serious complication occurs when the flap is cut too deeply in the cornea, causing the eye to rupture. • Over-correction or under-correction: Due to variations in healing and corneal response, some patients may be under corrected or over-corrected following the LASIK. Some patients may need to use glasses or contact lenses.
