Patent number: 7018409Abstract: Intraocular lenses include a lens body sized and adapted for placement in a mammalian eye and having a plurality of different optical powers, and a movement assembly joined to the lens body and adapted to cooperate with the mammalian eye to effect accommodating movement of the lens body in the eye. The lens body has an azonal, aspheric surface, with the correction power of the lens varying continuously and progressively from the optical axis to the periphery of the lens. Such intraocular lenses provide enhanced accommodation relative to the accommodation attainable using a spheric, monofocal IOL adapted for accommodating movement or an aspheric accommodating lens located in a substantially fixed position in an eye.Type: GrantFiled: September 13, 2002Date of Patent: March 28, 2006Assignee: Advanced Medical Optics, Inc.Inventors: Robert E.

Patent number: 6824563Abstract: An binocular lens system for improving the vision of a patient including first and second ophthalmic lenses. Each of these lenses is adapted for implantation in an eye or to be disposed on or in the cornea. The first lens has a first baseline diopter power for distance vision correction and the second ophthalmic lens has a second baseline diopter power for other than distance vision correction. The ophthalmic lenses may be intraocular lenses which are implanted in the eyes of a patient or has natural lenses or following removal of the natural lenses.Type: GrantFiled: February 18, 2003Date of Patent: November 30, 2004Assignee: Advanced Medical Optics, Inc.Inventor: Alan J.
