ABSTRACT:
A device that projects light rays and beams onto the eye in a predetermined pattern or arrangement of patterns, wherein the light rays or beams scatter in the eye tissues and which images of scatter are captured by video scanning cameras. The images are transferred into digital information for processing, storage, display or retrieval by a processing device which also determines the location, and position of the scattered light in space and prepares a mathematical representation of the light representing the shape, thickness, and relationship of the tissues of the eye.
