ABSTRACT:
An apparatus for detecting ophthalmic diseases such as a cataract in the lens of a patient's eye which includes means for focussing a laser beam at a selected spot in the lens of an eye, and according to which the light back-scattered from the eye are photoelectrically detected and converted into an electrical signal which is subsequently used to determine an autocorrelation function relating to the fluctuation of intensity of the back-scattered light over time, and to derive therefrom a protein particle distribution essential to ophthalmic disease detection.
