A corneal scanner.
A pocket-sized self-illuminated diagnostic instrument is described which projects a circle or a line, continuous or interrupted, upon the cornea. It is moved in all directions, thus rapidly scanning the cornea for any distortion of the reflected image, indicating or localizing surface or structural pathology.
