Abstract
Intraocular lenses for reducing the risk of posterior capsule opacification (PCO) are described herein. PCO can be reduced with an IOL design that increases the pressure at the posterior capsular bend, for example, by including a sharper edge design, an enlarged optical zone, and/or an increased vault height. An example ophthalmic lens can include an optic (200) including an anterior surface (202) defining an anterior side of the optic, a posterior surface (204) defining a posterior side of the optic, and an edge (210) arranged between the anterior and posterior surfaces. The edge and the posterior surface can form an angle, where the angle is less than about 90 degrees. Additionally, the ophthalmic lens can have an increased vault height. At least one of the angle or the increased vault height be configured to increase pressure on a capsular bend in a subject's eye.
