Abstract
A method is disclosed to determine the degree of cataractogenesis of a lens in vivo. By collecting and determining the intensity of light scattered from a measurement location in the lens and comparing this value to the intensity of light scattered by a normal, clear lens region or a calibrating element, it is possible to determine the degree of cataractogenesis at the specific measurement location. This data may be applied to an experimentally determined and theoretically deduced universal curve in order to determine quantitatively the degree of cataractogenesis at that particular location in the lens.
