Abstract

An intraocular lens (IOL) has an optic, a peripheral rim, and a reduced thickness region connecting the optic to the peripheral rim. The peripheral rim has a continuously curving outer edge that it does not include any tangents parallel to the optical axis either along its length or at the intersection of the outer edge with the anterior or posterior surfaces of the IOL.
