1. A method for in vivo detection of cataractogenesis in oscular tissue, comprising the steps of:

  • (a) producing a substantially monochromatic, coherent, collimated light;

    (b) causing the light to impinge on the ocular tissue;

    (c) collecting light that is scattered from the ocular tissue, the scattered light having a fluctuating intensity;

    (d) performing a mathematical analysis on the intensity and the fluctuations of the intensity of the collected light, thereby determining a signature of cataractogenesis, the signature including the intensity (Iimm) of the light scattered by immobile scatterers in the ocular tissue; and

    (e) determining from the signature the degree of cataractogenesis.
