For over 25 years doctors placed
incisions in the cornea to treat nearsightedness (myopia), farsightedness (hyperopia),
and astigmatism. In the early 1980s, they began looking at lasers to improve the precision and
predictability of altering the shape of the cornea. Researchers found that the Excimer laser could remove
tissue with up to 0.25 microns of accuracy. Now, in its second decade of use, the technologically advanced
Excimer laser has added a tremendous amount of precision, control and safety to the surgical correction of
vision errors. Using this remarkable technology, the cornea is reshaped to conform to your glasses or
contact lens prescription, thereby reducing or even eliminating the dependence on corrective lenses.
LASIK, which stands for Laser-Assisted In Situ Keratomileusis, offers a number of benefits over other
forms of laser vision correction because it is performed under a protective layer of corneal tissue.
As a result, there is less:
- Surface area to heal
- Risk of scarring
- Risk of corneal haze
- Postoperative discomfort
And vision usually returns more rapidly, often within a day or so. LASIK can also treat a higher range
of vision errors. Although postoperative results vary, almost 100% of patients are able to pass a
driver's license test without their corrective lenses. |
