About LASIK!
|
|
LASIK is the most recent advance in Laser Vision Correction. It stands
for Laser Assisted In-situ Keratomileusis, Compared to the original laser PRK, the
surface of the cornea remains largely intact, so that LASIK patients are more comfortable
and see well more quickly.
Your eye will be anesthetized with eye drops. You may feel some pressure or
stretching sensation from the eyelid holder, but there should be no pain. A sedative
is offered to help you relax. |

A fixation ring is applied to the eye to stabilize it and make it firm. The microkeratome then glides across the
surface of the cornea to lift a flap about 20% thickness. The flap is reflected back to expose the inner corneal tissue.
Your eye is precisely centered under the laser, while you look into a blinking laser
fixation light. The laser is programmed for your correction. Repeated pulses of the cool laser beam gently vaporize a programmed pattern of tissue to reshape the cornea, neutralizing your refractive
error. Your treatment will consist of multiple Laser pulses over
15 - 30 seconds. The doctor can stop the Laser any time, so
minor movement of your eye is not a problem. (See Animation) |

The flap is then returned to its exact original position. It will stick in place without sutures in 2-5 minutes. The doctor will check the flap again before you leave to confirm that the
flap is exactly in place. Eye shields are applied for protection.
Your vision will seem like you are under water for the first 12 hours or so. You may have a
mild foreign body sensation. We recommend you take Tylenol when you arrive home and then take a nap.
Many people feel fine and see well enough to drive the next day, older patients with higher
amounts of correction may take a little longer.
