Topography
Epithelium
Embryologically, the lens epithelium is derived from the cells of the original lens vesicle that did not differentiate into primary lens fibers. The anterior or axial lens epithelium consists of a single layer of cuboidal cells. The basilar surface of the anterior epithelium is oriented toward the anterior lens capsule. The equatorial cells are mitotically active and appear more elongated as they differentiate into lens fibers. Epithelial cells are not typically observed posterior to the lens equator (see Fig 9-2).
