ABSTRACT:
An inflatable, intraocular lens is disclosed for implanting within the lens capsule of an eye following removal of the biological contents of the lens capsule. The lens comprises a thin-walled lens skin forming a substantially enclosed, collapsible sac made of a flexible polymeric material and having a wall thickness no greater than about 0.15 millimeter. The lens skin further has an exterior shape when inflated which is substantially the same as the shape of the biological content of the lens capsule of a normal eye. A pair of longitudinal, flexible tubes extend from the lens skin, with the lumen of each tube communicating with the inside of the sac formed by the lens skin. In a collapsed, folded condition, the lens skin can be inserted into the lens capsule of an eye through a relatively small incision in the eye, with the lens skin being adapted for inflation through the pair of tubes after the lens skin has been inserted into the lens capsule of the eye. The lens skin is filled with a liquid which will cure to an elastomeric material having proper optical qualities. An insertion device, a method of inserting and filling the lens skin with a liquid capable of curing to form a proper elastomeric material, and an instrument for aiding in removing bubbles from the inflated lens skin during the filling procedure are also disclosed.
