New Photokeratoscope Utilizing a Hemispherical Object Surface

Not Accessible

Your library or personal account may give you access

Abstract

A photokeratoscope is described which makes it possible to record in a single photographic exposure the contour of the entire corneal surface of the eye. This has been accomplished by using a hemispherical object surface located such that its center of curvature coincides with the center of curvature of the cornea being photographed. The reflection of this surface is photographed through a small hole in the object surface. A brief history of the development of photokeratoscopy is presented. Photographs taken thus far verify the spherical nature of the central zone of the cornea.
