Abstract
An IOL system includes a capsular ring having a concave exterior surface extending around its circumference that is configured, upon insertion into a capsular bag of a patient's eye, to engage an equatorial region of the capsular bag. The concave exterior surface extends between an anterior surface and a posterior surface of the capsular ring. A first one or more flaps are arranged on the anterior surface such that at least a portion of each of the first one or more flaps, upon insertion into the capsular bag of a patient's eye, engages an anterior portion of the capsular bag. Similarly, a second one or more flaps are arranged on the posterior surface such that at least a portion of each of the second one or more flaps, upon insertion into a capsular bag of a patient's eye, engages a posterior portion of the capsular bag.
