In the extraction of senile cataract by the flap operation downward, it occasionally happens that an unintentional innervation of the ocular muscles, immediately after the section is completed, forces the lens, with its capsule unruptured, out of the eye. The lens then ordinarily preserves its senile, flattened form, but at times I have observed that with liquefaction of the cortex the extruded lens in its intact capsule exhibits the round form which is found post mortem in the eyes of the young. Since the liquefied cortex can have no particular elasticity, this fact can be explained only as being due to the elasticity of the lens capsule, and it is also conceivable that an elastic membrane filled with soft contents should naturally take on a spherical shape when this is not prevented by a counter-traction. The greater thickness of the anterior capsule thus explains also its greater curvature in accommodation. . . . [Full Text of this Article]
