Keratoconus

Keratoconus is a genetic condition of the cornea, the front window of the eye. The cornea is very important and is one of the main contributors to refractive errors. Keratoconus is a condition where the cornea’s structural integrity is compromised and this leads to progressive thinning of the cornea, which leads to dramatic vision changes.

These vision changes can be quite irregular, to the point that oftentimes even correction with spectacles is not enough. In these cases, specially designed contact lenses might be the best tool to recover the vision for someone who suffers from keratoconus.

Current technological advances have allowed eye specialists to be able to strengthen the structural integrity of the cornea for those who have keratoconus using a procedure called collagen cross-linking (CXL). CXL can successfully halt the progression of keratoconus before any contact lenses are fitted to recover vision to the eyes.

One of the major risk factors for the progression of keratoconus is eye rubbing, so if you are in the habit of rubbing the eyes, you may want to visit your optometrist to talk about ways to help avoid this habit.
