ABSTRACT:
The invention contemplates an improved lens implant for use in ophthalmological surgery, the lens being a replacement for a cataract-clouded natural lens, and the replacement being installed via the pupil at the iris as the operative step following removal of cataract material. The invention features flexible haptic structure assembled to and retaining an optically finished lens element. The haptic structure integrally includes two asymmetrically defined generally diametrically opposed stabilizing feet which extend radially outward of the region of lens retention and which are each characterized by an arcuate peripheral band adapted for positioning engagement with structural features within one of the chambers of a human eye. Loop formations local to a single peripheral band and to the region of lens retention define localized openings adapted for reception of suture, pincer or other manipulative instrumentalities.
