Whole pig lenses were fixed, critical-point dried and fractured, and the internal surfaces examined with a scanning electron microscope. At various locations from the equator to the center of the lens four types of fibers can be distinguished. The superficial fibers have small interdigitations. Cortical lens fibers, which are hexagonal in shape exhibit well developed “ball-and-socket” junctions. Other cortical fibers appear slightly undulated and show fine granulations. The core lens fibers are characterized by microplicae on the cell surfaces and by a more rounded or rectangular form. Results are discussed in relation to previous electron-microscopic studies of other species.
