This is the first reported electron-microscopic evaluation of lens changes in electric cataracts. The anterior subcapsular opacity of these cataracts was composed of elongating and proliferating epithelial cells. Each elongating cell was surrounded by its own capsule. The posterior cortex of the lens was diffusely opaque and fibers in this region contained many small dense circular bodies. The anterior lens changes appear to be due to an electrically induced proliferation and abnormal differentiation of epithelial cells while the posterior changes involve faulty formation of lens fibers.
