Studies on human cataracts. II. Correlation between the clinical description and the light-scattering parameters of human cataracts.

Eight lenses with nuclear cataracts have been classified. The light-scattering properties of the eight lenses were obtained with thin sections cut perpendicularly to the posterior-anterior axis. Analysis of the light scattering envelop in the I and I+ models yielded eight structural parameters that describe the density and orientation fluctuations. The variation of these parameters within each less corresponded well to the clinical description obtained from the stereoscopic photos.
