Keratoconus is a bulging of the cornea. When the cornea bulges vision can get very blurry and unstable along with double vision and light sensitivity.  

Keratoconus can be caused by a combination of genetics, hormones, and environmental factors such as rubbing the eyes.

Early-stage keratoconus can be treated with soft contacts or glasses, but as the cornea bulges further and distortions increase, Scleral Contact lenses are the preferred treatment.

Scleral lenses are large contact lenses that fit on the sclera and over the cornea.  Since the lens does not touch the cornea, saline fluid fills the space in between to smooth everything out and give patients the best possible vision and comfort.

Scleral lenses sit on the sclera and vault over the cornea. The space between the cornea and the lens is filled with a liquid reservoir
