Laser eye surgery that reshapes the cornea to correct refractive errors.
Full Definition
Laser-Assisted in Situ Keratomileusis (LASIK) is a popular refractive surgery procedure that uses an excimer laser to reshape the corneal stroma and correct myopia, hyperopia, and astigmatism. The procedure involves creating a thin corneal flap using either a microkeratome or femtosecond laser, lifting the flap to expose the underlying stroma, applying the excimer laser to remove precise amounts of tissue, and then repositioning the flap. LASIK offers rapid visual recovery and minimal discomfort compared to surface ablation techniques, making it one of the most commonly performed elective surgical procedures worldwide.
