Initial Correction Keratoconus
Running, not enrolling · Not applicable
Conditions studied: Keratoconus
In brief
Keratoconus is a non-inflammatory, progressive disease in which corneal irregularity increases. As the condition develops, more advanced forms of optical correction are needed to improve vision for patients. Until recently, small diameter corneal gas permeable lenses were considered the primary mode of correction for patients with keratoconus. Now, however, practitioners have multiple options for reducing the optical aberrations caused by keratoconus, including scleral lenses. As of yet, no single option for optical correction has been identified as the preferred mode of correction in terms of overall patient satisfaction with vision, comfort, and ease of use. The order in which various forms of optical correction would be most logically introduced has yet to be determined. This is a study comparing small diameter corneal gas permeable and large diameter scleral lenses in individuals with keratoconus. This study will prospectively compare visual satisfaction and ease of use between corneal gas permeable and scleral lenses for patients with mild to moderate keratoconus.
