What is lasik eye surgery?
Laser-Assisted In Situ Keratomileusis (LASIK) is a safe, reliable and painless way to improve vision by changing the way light is bent, or refracted, as it passes through the cornea, so that it is properly focused on the retina and allows objects to be seen clearly. During the LASIK procedure, the surgeon creates a thin flap in the surface of the cornea with a device called a microkeratome blade. This procedure is performed under local anesthesia so that pain is minimized. The corneal flap is then lifted and an excimer laser beam reshapes the cornea’s curvature to improve vision.
Am i a candidate for lasik?
The ideal LASIK candidate includes someone who is over 18 years old, has stable vision and has a healthy cornea that is thick enough for a flap. After undergoing the procedure, patients experience immediate vision improvement and can often return to work the very next day.
LASIK procedures involve the creation of a flap followed by the laser to reshape it. The flap is then replaced over the area that has been lasered. Visual improvement is quick (usually within 24 hours) and post-operative discomfort is minimal.
A thin flap of cornea is created that looks like a perfect soft contact lens. The flap is then moved up out of the way of the laser temporarily. The excimer laser removes a minute amount of the cornea beneath the flap. The pattern of cornea removed depends on the correction necessary. The flap is then moved back to its original position, completely covering the treated area. The flap sticks down and adheres within several minutes.
Finally, the flap is closed and covered with a protective contact lens. The entire procedure takes about 15 to 30 minutes per eye.
