Understanding Keratoconus

Keratoconus is an eye disease that causes the cornea to thin and bulge. This bulge generally takes on the appearance of a cone. As light enters the eye, it becomes distorted by the cone causing vision abnormalities. Most opt to use scleral lenses. These are gas permeable lenses but cover a larger area of the eye than a standard rigid lens. These lenses don’t put pressure onto the cone shape of the eye. The reduced pressure results in a more comfortable fit for patients.

​​​​​​​The advanced scleral lens also doubles as a protective prosthetic shell. There are special requirements to qualify for this lens though, so check with your eye care professional if this is an option for you.
