Abstract: In this method an artificial lens is implanted in an eye in which the crystalline portion of the natural lens has been surgically removed through an opening made in the anterior wall of the lens capsule and through a small incision in ocular tissue at the front of the eye. This method utilizes an expansible bag that has a transparent body portion containing a cavity and an entrance opening to the cavity through which filler material can be introduced into the body portion. The body portion of the bag is inserted through the small incision and through said opening in the anterior wall of the lens capsule into a position where at least a portion of the body portion is located within the still-remaining portion of the lens capsule. Then the body portion is distended by introducing filler material through said entrance opening, and the distended body portion is located within the still-remaining portion of the lens capsule in a location adjacent the posterior wall of the capsule.
