ABSTRACT:
A narrow profile, glare reducing, posterior chamber intraocular lens comprises an optic having an anterior surface and a posterior surface and an optical axis. The posterior surface is formed having two adjacent peri-axial, stepped imaging zones, the two imaging zones having the substantially the same optical power. A transition zone between the two imaging zones preferably has a surface of continuous curvature shaped to reduce direct glare from light incident on the transition zone in an individual's eye in which the intraocular lens is implanted by internal reflection of direct light incident on the transition zone. Attachment members joined to the optic position the intraocular lens in an eye with the optical axis of the optic generally aligned with the optical axis of the eye. In variations, the transition zones are formed at the optic edge to minimize direct and indirect in the eye of an individual wearing the intraocular lens.
