Abstract
An apparatus is disclosed for using quasielastic light scattering to determine the degree of cataractogenesis of a lens in vivo. By collecting and analyzing light scattered from the lens, it is possible, using the autocorrelation function or the power spectrum, to separate the fluctuations into two components: one caused by fast diffusing proteins and one caused by slow diffusing protein aggregates. 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.
