Fig. 1. Light micrographs of the anterior (A) and posterior surface (B) of a normal 40-year-old human lens. Faint, complementary, complex star suture patterns are visible. Although suture branches are resolvable, the individual fibers and their overlapped ends that make up the suture branches are not. The yellow coloration of this lens is an artefact of glutaraldehyde fixation rather than a function of age.
