Correction of keratoconus with rigid gas-permeable contact lenses

This study analyzed the feasibility of fitting keratoconus-affected corneas with nonkeratoconus rigid gas-permeable (RGP) contact lenses. We retrospectively studied patients with a diagnosis of keratoconus in the past 10 years who were fitted successfully with nonkeratoconus RGP lenses by the same physician. Results confirmed nonkeratoconus RGP lenses as the first-line correction tool. Additionally, we found a simple equation to speed the choice of the base curves of the lenses.
