Quick Answer: LASIK (Laser-Assisted In Situ Keratomileusis) is a laser eye procedure that reshapes the cornea to correct short-sightedness, long-sightedness and astigmatism, often reducing or removing the need for glasses or contact lenses.
A thin flap is created in the cornea and lifted. A computer-controlled excimer laser then reshapes the tissue underneath, and the flap is repositioned, where it adheres naturally within minutes. The laser part of the procedure typically takes around 10–15 minutes.
Femto-LASIK is a bladeless variation in which the corneal flap is created with a femtosecond laser rather than a blade. Flapless options, such as Schwind ATOS SmartSight, avoid creating a flap altogether.
LASIK is generally recommended from age 18, once the eyeball has stopped growing and the prescription has been stable for at least a year. It is usually not recommended with an unstable prescription, significantly dry eyes, or corneal conditions such as keratoconus. A comprehensive evaluation confirms eligibility.
