LASIK (Laser in-situ Keratomileusis) is a form of laser refractive surgery to correct your vision. During LASIK surgery, a corneal flap is created with a Femtosecond laser. The corneal flap is lifted and an Excimer laser with eye-tracking function is used to reshape the cornea to correct the refractive error with an all-laser, bladeless technique. The corneal flap is then replaced.
