  • Device and method for measuring the curvature of the cornea
    Patent number: 4159867
    Abstract: A device and method are disclosed for measuring the curvature of the cornea of the human eye. The device utilizes a continuous, curved surface plate positioned in front of the eye and having a telescope extending through the surface plate such that its optical axis is aligned with the eye. Several object points are generated on the surface plate within the field of vision of the eye and are formed also on the image plane of the eye. Detection devices, located within the telescope measure the positions of such image points in relation to the optical axis. The radius of curvature of the cornea can be determined from this measurement.
