Definition: Blade-free Laser Assisted In-Situ Keratomileusis, or LASIK, is a refractive surgery procedure which uses the excimer laser, applied to the cornea under a thin flap of corneal tissue, to help which correct refractive error, decreasing or eliminating the need for glasses or contact lenses. With Blade-free LASIK, a laser is used for all portions of the procedure.
How Does LASIK Work?
LASIK surgery works by sculpting the cornea in a precise manner to correct refractive errorBy changing the corneal shape, light becomes focused on the retina, allowing clear vision. During LASIK surgery, a very thin flap is created on the front of the cornea. The flap is then folded back, and the laser applied to the underlying corneal tissue in a precise manner that can correct nearsightedness, farsightedness and/or astigmatism. The flap is then replaced, protecting the reshaped cornea underneath. This protective flap can be created in two ways. In the first, a very fine surgical steel blade, called a microkeratome is used to create the flap. With Blade-free LASIK, a laser beam is used to create the corneal flap. Several laser technologies can be used to create the Blade-free LASIK flap. One of the most common such lasers is the Intralase laser.
