Laser eye surgery, commonly known as LASIK (Laser-Assisted In Situ Keratomileusis), is a procedure used to correct vision problems like nearsightedness, farsightedness, and astigmatism. 

In this method, a specialized laser reshapes the cornea (the clear front part of the eye) to allow light entering the eye to be properly focused on the retina, thus improving vision clarity. The surgery begins with creating a thin flap on the cornea's surface, which is then lifted to allow the laser to reshape the underlying corneal tissue precisely. 

After the cornea is reshaped to correct the specific refractive error, the flap is placed back, where it naturally adheres without stitches. This procedure is quick, typically painless due to numbing eye drops, and has a short recovery time, with many patients noticing improved vision within a day.
