The primary benefit of LASIK is that it can significantly improve vision. The procedure reshapes the cornea, the clear front part of the eye, to allow light to focus properly on the retina, which improves vision. Patients usually experience improved vision within a few days after surgery and often no longer require corrective eyewear.

Another benefit of LASIK is that it has a relatively quick recovery time. Patients are usually able to return to their normal activities within a day or two after the procedure, and most experience little to no discomfort during the recovery process.

LASIK provides long-lasting results, and most patients experience significant improvement in their vision for many years after the surgery. While the procedure cannot prevent age-related changes in vision, it can correct vision problems that may have been present for many years.
