Laser Assisted In Situ Keratomileusis – LASIK
A technique for reshaping corneal tissue to help you see better without glasses or corrective lenses.
This is the most commonly performed laser eye treatment. For LASIK two different types of laser are used. First, a femtosecond laser creates a thin protective layer by tracing a 3D pattern of tiny gas bubbles through the corneal tissue. This hinged layer is lifted back by the surgeon before an excimer laser reshapes the cornea to correct focus.
An excimer laser, which produces a concentrated beam of cool ultraviolet (UV) light. Each pulse of the laser can remove a tiny part of corneal tissue. LASIK can be used to correct, Farsightedness (hyperopia), Nearsightedness (myopia), and Blurred vision caused by an abnormally shaped cornea (astigmatism).The protective flap is then replaced to complete the procedure.After approximately 3-6 hours the surface cell layer heals around the edge of the flap and sight begins to improve. By the day after surgery, most people are able to see well enough to work and drive a car.
