title: Pathologico-optic approach to cataract and lens.
abstract: From the weight of the lenses of patients with senile cataract, ultrasonic measurements of the eyes of patients with acute diabetic refractive changes, and calculations on the basis of Legrand's theoretical eye, it appears that the conclusion can be drawn that these refractive changes are due to alterations in the refractive indices of the lens.
