A Closer Look at Keratoconus
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 evidence that the
disease has genetic origins, possibly made worse by environmental factors. It normally affects both
eyes, though it typically progresses at different rates. In most people, keratoconus begins during
their teen years and slowly worsens before stabilizing in their 30s or 40s.
Keratoconus is estimated to affect one in 2,000 people across all races.
It is normally treated with rigid contact lenses which are contoured to address the bulging cornea
and to improve vision. A proper contact lens fit is crucial to obtain adequate vision and wearing
comfort. Poorly fit or outdated contact lenses can be uncomfortable and lead to additional
complications like corneal abrasions, scarring or infection.
In mild cases, glasses and soft contacts can be effective, but in more advanced cases, these no
longer work well.
