The subject is a 35-year-old woman diagnosed with keratoconus since she was 18 years old. She had previously worn corneal rigid gas-permeable (RGP) contact lenses for the last 2 years. However she experienced discomfort and intolerance. Keratoconus is a noninflammatory, elastic corneal disorder caused by progressive thinning and distortion of the central cornea. The condition is bilateral but frequently asymmetric. Scleral lenses are widely fitted for keratoconus patients. This is due to the possibility of scleral lenses to vault over the cornea. Therefore, they can be experienced as more comfortable than rigid lenses.
