INTRAOCULAR LENS FOR INHIBITING CELL GROWTH AND REDUCING GLARE

摘要

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, preferable both of such faces, forms a peripheral corner located at a discontinuity between the peripheral edge and the intersecting face or faces. The present IOLs inhibit cell growth from the eye in front of or in back of the optic and reduce glare obtained in the eye in which the IOL is located.

主权项

1. An intraocular lens, comprising:
a centered optic sized and adapted for placement in the capsular bag of an eye and configured to direct light toward the retina of the eye, the optic having a central optical axis, an anterior face and an opposed posterior face, and a peripheral edge disposed about the central optical axis between the anterior face and posterior face, the peripheral edge comprising:
a linear edge portion;a non-discontinuous convex portion comprising at least one curvature that is substantially greater than the curvature of the anterior face, the non-discontinuous convex portion smoothly blending the anterior face with the linear edge portion; anda peripheral corner edge located at a discontinuity between the peripheral edge and the posterior face for inhibiting cell growth onto the optic.
