| LASIK is a surgical procedure
that can eliminate a person’s dependency on glasses or contact
lenses by permanently changing the shape of the cornea of the eye.
For clear vision, the eye's cornea and lens must bend (refract)
light rays properly, so that images are focused on the retina. If
the light rays aren't clearly focused on the retina, the images
you see are blurry.
This blurriness or refractive error is caused by an imperfectly
shaped eyeball, cornea, or lens. LASIK uses an ultraviolet laser
to precisely remove corneal tissue to correct the shape for better
focusing.
The surgery is performed most often on people who have myopia (nearsightedness) |
