Keratoconus
(ker-uh-toe-KOH-nus) occurs when your cornea — the clear, dome-shaped front
surface of your eye — thins and gradually bulges outward into a cone shape.
Keratoconus is a progressive disease. It
can occur in one or both eyes and often begins during a person's teens or early
20s.
LASIK is not a solution for this
progressive disease due to several factors, including the thinning of the
cornea and the shape of the cone. There
are, however, effective solutions available for this disease. In addition to
custom toric lenses, gas permeable lenses and other lenses, Keratoconus can
often be best treated with:
- KeraSoft lenses (Bausch + Lomb).
These high-water silicone hydrogel lenses can correct up to 20 diopters (D)
of nearsightedness or farsightedness and up to -12 D of astigmatism.
- NovaKone lenses (Alden Optical).
These medium-water hydrogel lenses can correct up to 30 D of
nearsightedness or farsightedness and up to -10 D of astigmatism.
- Corneal inserts received FDA approval for treating keratoconus in
August 2004. The tiny plastic inserts are placed just under the eye's
surface in the periphery of the cornea and help re-shape the cornea for
clearer vision.
- A procedure call corneal crosslinking, which
strengthens corneal tissue to halt bulging of the eye's surface.
- Corneal transplants are sometimes the best
solution for people with this disease.
