Abstract
A method and apparatus for detecting cataractogenesis is disclosed. Quasielastic light scattering data are collected from the lens of an individual to be tested for cataractogenesis. The data are collected from specific and reproducible sites within the lens by means of measurements made using a reticle in the apparatus and processed by an autocorrelator. The data from the autocorrelator are then fit to a double exponential form of autocorrelation function and the resulting functional form is transformed to produce at least one dimensionless parameter F.sub.mos. This parameter has been found to change predictably with the individual's age and, accordingly, is useful in detecting and determining the degree of cataractogenesis in the individual.
