An instrument for measuring the contour of the cornea.
An instrument designed to measure quantitatively the contour of the human cornea is described. This apparatus can be used to btain enlarged cross sections of the cornea without harming the eye in any way. An image of a brightly illuminated slit is projected onto the cornea. The intersection of the slit image with the surface of cornea constitutes a section plane through the cornea. The undistorted, enlarged images of selected sections are recorded photographically as corneagrams.
