Abstract

A narrow profile, glare reducing, refractive monofocal intraocular lens (80) is described that comprises an optic (82) having an anterior surface and a posterior surface and an optical axis. One of the anterior and posterior surfaces is formed having two adjacent peri-axial, stepped imaging zones (90), (92), the two imaging zones having the substantially the same optical power that is preferably outside the -5 to +5 diopter range. A transition zone (94) between the two imaging zones preferably has a continuously variable surface curvature that reduces both indirect glare (caused by light refraction) and direct glare (caused by light diffraction) in an individual's eye in which the intraocular lens (80) in implanted. The transition zone (94) surface may alternatively be continuously curved or variably curved to reduce direct glare and indirect glare, respectively. Attachment members (84), (86) joined to the optic (82) position the intraocular lens in an eye with the optical axis of the optic (82) generally aligned with the optical axis of the eye.

Claims

26AMENDED CLAIMS[received by the International Bureau on 01 October 2002 (01.10.02); original claims 1-22 replaced by amended claims 1-20 (5 pages)]
