LASIK (Laser-Assisted In Situ Keratomileusis) is a popular refractive surgery used to correct vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The procedure reshapes the cornea using an excimer laser, allowing light to focus correctly on the retina for clearer vision. A thin flap is created on the cornea, lifted to expose the underlying tissue, and then precisely reshaped before the flap is repositioned. LASIK is quick, virtually painless, and provides rapid visual recovery, often reducing or eliminating the need for glasses or contact lenses.
