The peripheral edge has one or more curved or angled surfaces that reduce glare within the IOL. For instance, a rounded transition surface on the anterior side of the peripheral edge diffuses the intensity of reflected light, or a particular arrangement of straight edge surfaces refracts the light so as not to reflect, or does not reflect at all. The intersection of the peripheral edge and at least one of the anterior face and the posterior face, preferably both of such faces, forms a peripheral corner located at a discontinuity between the peripheral edge and the intersecting face or faces.Type: ApplicationFiled: August 27, 2002Publication date: March 27, 2003Applicant: Allergan Sales, Inc.Inventors: Marlene L.

Publication number: 20030055498Abstract: An intraocular lens implantable in an eye includes an optic for placement in the capsular bag of the eye and for directing light toward the retina of the eye. The optic has a central optical axis, an anterior face, an opposing posterior face and a peripheral edge between the faces. The peripheral edge has one or more curved or angled surfaces that reduce glare within the IOL. For instance, a rounded transition surface on the anterior side of the peripheral edge diffuses the intensity of reflected light, or a particular arrangement of straight edge surfaces refracts the light so as not to reflect, or does not reflect at all. The intersection of the peripheral edge and at least one of the anterior face and the posterior face, preferably both of such faces, forms a peripheral corner located at a discontinuity between the peripheral edge and the intersecting face or faces.Type: ApplicationFiled: August 6, 2002Publication date: March 20, 2003Applicant: Allergan Sales, Inc.Inventors: Marlene L.
