Keratoconus Conditions

Keratoconus is a disease that causes a progressive thinning of the
cornea, the clear front portion of the eye. As a result of this condition,
the normal outward pressure from within the eye causes the cornea
to progressively bulge into a cone-like shape. Keratoconus rarely
results in total blindness although it can significantly impair vision
and, according to experts, lead to the need for a corneal transplant
(in up to 20% of cases). |
While nobody knows the cause of keratoconus, there is good evidence that
the disease has genetic origins, and possibly made worse by environmental
factors. It normally affects both eyes, though it typically progresses at
different rates. In most people, keratoconus begins during there teen years
and slowly worsens before stabilizing in their 30's or 40's.
Keratoconus is estimated to affect one in 2,000 people across all races.
It is normally treated with rigid contact lenses to reshape and flatten
the pronounced curve of the bulging cornea and to improve vision. A proper
contact lens fit is crucial to obtain adequate vision and wearing comfort.
Poorly fitting or outdated contact lenses can be uncomfortable and lead
to additional complications like corneal abrasions, scarring or infection.
A keratoconus-like condition is a rare condition that develops after a routine
lasik procedure. This condition is called ectasia. Although generally less
severe and less disabling than Keratoconus, ectasia may be associated with
throbbing visual symptoms. Prior to Intacs, there were no surgical options
available to treat this condition. Now, by the placement of Intacs, a patient's
visual functionality can be greatly improved.
