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.
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.
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.
