LASIK is a laser eye surgery that has proven to be effective in correcting vision and lessening (and oftentimes eliminating) the need for glasses or contact lenses. Many different vision problems, including nearsightedness, farsightedness, and astigmatism, can be treated with LASIK, which is a procedure that permanently reshapes the cornea of your eye. LASIK is one of the most commonly performed procedures in the world for vision correction, with predictable results and low risk.
