Which is the thinnest pa of the lens of eye?
Anterior pole
Posterior pole
Posterior capsule
Apex
The lens is thinnest at the posterior pole. The crystalline lens is surrounded by a lens capsule. Lens capsule is a thin transparent elastic membrane secreted by the lens epithelial cells largely composed of type IV collagen. The capsule is 11- 15microm thick at the anterior pole. The posterior capsule thickness decreases to a minimum at the posterior pole to about 4microm. Ref: Adler's Physiology of the Eye: Expe Consult by Leonard A Levin, Page 47
