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 the lens and are processed by an autocorrelator. The data from the autocorrelator are then fit to an autocorrelation function having a component which has a second derivative less than or equal to zero. This autocorrelation function 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.
