Abstract
An accommodating lens is designed to be inserted into a substantially intact capsulary bag having a capsulorexis opening in its anterior wall. The lens has an accommodating portion adapted to be affixed to the anterior wall of the capsulary bag adjacent the opening. The focal length of the deformable portion is alterable by insertion of a deforming material into the deformable portion thereof. In another embodiment, the focal length of a second deformable portion of the lens is varied by insertion or extraction of deformable material into or from the second portion.
