Keratoconus and Corneal Irregularities (Pellucid Marginal degeneration/Corneal Ectasia)
If you have keratoconus or another corneal irregularity, day to day activities, such as driving, reading, or even watching tv may be difficult or impossible with traditional means of correction. Scleral lenses work to reduce this irregularity and restore the vision (and life) you once had.
What is it?
The clear window part of the front of the eye begins to bulge and form a cone shape
The cone shape makes vision blurry and starts to distort vision
What causes it?
The exact cause is unknown but there is thought to be a genetic component to it.
It has also been associated with eye allergies, excessive eye rubbing, and connective tissue disorders like Marfans Syndrome and Ehlers-Danlos
Onset usually occurs during the late teen years and can be progressive for the next 20 years.
What are the symptoms?
Distorted or blurry vision is the most common along with light sensitivity and glare
It can affect one or both eyes and each eye can have different symptoms.
Progression tends to be slow, but in some cases it can happen quite rapidly
Later stages will notice increased distortion, excessive astigmatism, and corneal scarring
How is keratoconus treated?
Mild early stages are treated with traditional glasses and contacts
Mid to later stages can get optimal vision with highly customizable scleral lenses that recreate an artificial corneal surface. SLC works specifically with these lenses and patients to optimize patients vision
Collagen cross-linking and surgical procedures such as intacs and corneal transplants are options for patients with progressive advanced keratoconus.
