It’s important to remember that even minor, everyday corrective eye treatments carry some risk, including wearing contact lenses. In recent studies and our experience, most patients achieve excellent results without significant complications. Serious complications appear to be rare.
Some patients do require a second treatment in order to get the vision that they desire. If a second treatment is necessary, it is usually performed several weeks or months after the first procedure.
Infections after LASIK have been reported, but are rare. Occasionally, your surgeon may cancel your procedure if the flap created is not adequate. Your LASIK can be rescheduled for about three months later. Trauma to the eye shortly after the procedure, while the eye is still healing can cause complications. If a patient is hit in the eye after the procedure, the flap can be moved, making it necessary to surgically reposition the flap. Care should be taken to avoid having anything strike the eye and to avoid rubbing the eyes for several months after the procedure.
Occasionally, some epithelial (skin-like) cells on the surface of the eye can grow underneath the flap and cause problems. This can usually be resolved by lifting the flap, brushing away cells, and replacing the flap.
Most patients experience halos around lights and some starbursts or glare at night for several weeks to months after LASIK surgery. In general, these are noticeable but not debilitating, and usually are resolved within six months to a year after the procedure.
