Abstract
A modular intraocular lens (IOL) with a ring configured to prevent glare artifacts. The ring includes a flange on the posterior rim, in which an anterior surface on the flange has a first profile and a posterior surface of the flange has a second profile non-parallel with the first profile. Non-parallel surfaces of the flange can be configured to defocus light transmitted at off-axis angles through an optic and the flange.
