LASIK eye surgery is a common vision-correcting procedure that has the potential to eliminate the need for glasses or contact lenses for patients. The eye surgeon uses a laser to reshape the cornea so that light focuses on the retina correctly. The surgery has a very high success rate, with around 96 percent of patients achieving desired results. However, like any surgery, not everyone is a good candidate for LASIK. There can be factors that make the risk of complications outweigh the benefits.
