  • Automated hand-held keratometer
    Patent number: 5585873
    Abstract: An automated portable keratometer includes a hand held housing and is battery powered. A projection system projects collimated light sources at equal converging angles to an optical axis which extends outside the housing. A camera, including an imaging device, and telocentric objective lens are aligned along the optical axis in the housing. The projection system projects a known pattern of collimated light sources onto a patient's eye. The reflected images of these light sources is captured by the camera and imaging device. Derivation of the distances between certain reflected images can be converted by known algorithms into radii of curvature of the eye. Alignment leveling, and other features can be included with the keratometer. The device can also be used to measure other curved surfaces.
