Keratoconus is a condition in which the cornea is distorted in shape, resulting in poor vision. This condition can be helped with a highly customized gas permeable contact lens.
In advanced stages, keratoconus can result in thinning and scarring of the cornea. Corneal topography (a map of the cornea surface) can be used to monitor keratoconus and watch for progression. In some cases, a cornea transplant and scleral contact lens is necessary to improve vision.
