This highly specialized laser uses a cool ultraviolet light beam to remove (“ablate”) microscopic amounts of tissue from the cornea to reshape it so it more accurately focuses light on the retina for improved vision.
For nearsighted people, the goal is to flatten the cornea; with farsighted people, a steeper cornea is desired.
Excimer lasers also can correct astigmatism by smoothing an irregular cornea into a more normal shape. It is a misconception that LASIK cannot treat astigmatism.
After the laser reshapes the cornea, the flap is then laid back in place, covering the area where the corneal tissue was removed. Then the cornea is allowed to heal naturally.
Laser eye surgery requires only topical anesthetic drops, and no bandages or stitches are required.
In conjunction with St. Mary’s Laser/Advanced Surgery Center, hundreds of area patients have been treated for eye disease such as glaucoma, secondary cataracts, retinal deterioration, retinal hemorrhages, retinal holes or tears, and diabetic retinopathy.
