摘要:
A foldable intraocular lens(10) for providing vision contains an optic body(11) that includes an optical zone(12) and a peripheral zone (13) entirelysurrounding the optical zone. The optic body has an anterior face (14), asubstantially opposing posterior face (18), an optic edge (20), and an opticalaxis (22). The anterior face comprises a central face (24), a peripheral face(28), and a recessed annular face (30) therebetween that is disposed posteriorto the peripheral face. The intraocular lens further comprises at least onehaptic (32) that is integrally formed with the peripheral zone. The hapticcomprises a distal posterior face (34), a proximal prosterior face (38), and astep edge (39) disposed at a boundary therebetween. The haptic furthercomprises a side edge (40) disposed between the optic edge and the step edge.The proximal posterior face and the posterior face of the optic body form acontinuous surface (48). An edge corner (50) is formed by the intersection ofthe continuous surface with the optic edge, the side edge, and the step edge.
