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.

A method for in-vivo inspection of ocular tissue at a specific site comprising: (a) providing a source of substantially monochromatic, coherent, collimated light; (b) focusing light from the source on a first measurement location of a subject\s ocular tissue wherein said first measurement location corresponds to the clearest area of the subject\s ocular tissue; (c) collecting light scattered by the first measurement location; (d) converting the light scattered by the first measurement location into an electrical signal representative of the intensity of the light scattered by the first measurement location (Ifo); (e) storing the value of Ifo for later reference; (f) focusing light from the source on a second measurement location of a subject\s ocular tissue wherein said second measurement location corresponds to the area of the subject\s ocular tissue which is to be examined; (g) collecting the light scattered by the second measurement location; (h) converting the light scattered by the second measurement location into an electrical signal representative of the intensity of the light scattered by the second measurement location (Itot); and, (i) comparing the value of Itot to that of Ifo to determine the degree of cataractogenesis at the second measurement location of the ocular tissue.
