Keratometer was developed under the guidance of Optometry center. This instrument can give a precise examination of the radius of curvature of the anterior corneal surface. This measurement is utilized to fit contact lenses and to monitor corneal changes produced through the wear of contact lenses. Keratometer is occasionally used to assist in the recognition of certain comeal abnormalities and to check the radii of curavature of both hard and soft contact lenses. The program can be operated with considerable ease.
