Laser-Assisted in Situ Keratomileusis (LASIK) is a refractive eye surgery used to correct vision issues such as myopia, hyperopia, and astigmatism. The procedure begins with the application of numbing eye drops to ensure patient comfort. Once the eye is fully anesthetized, a microkeratome or a femtosecond laser is used to create a thin, circular flap in the cornea. The surgeon then carefully lifts this flap to expose the underlying corneal tissue. An excimer laser, which uses ultraviolet light, is applied to reshape the cornea by removing precise amounts of corneal tissue based on the patient's specific refractive error. This reshaping allows light entering the eye to be properly focused onto the retina, thus improving vision.

Following the corneal reshaping, the surgeon gently repositions the flap back over the treated area. The corneal flap adheres naturally without the need for stitches due to its inherent bonding properties. The entire LASIK procedure typically takes about 10 to 15 minutes per eye, with the actual laser treatment often lasting less than a minute. Post-procedure, patients may experience mild discomfort, dryness, or blurred vision temporarily, but these symptoms typically resolve within a few days. Recovery is generally quick, with most patients noticing significant improvement in vision within 24 hours. Follow-up visits are scheduled to ensure proper healing and to address any complications, though serious problems are rare.
