Abstract
An intraocular lens (IOL) includes an optic for focusing light, an outer ring for supporting the optic in a capsular bag of an eye and a plurality of radially spaced apart, elongated intermediate members connecting the optic to the outer ring. The intermediate members are configured to convert radial forces exerted by the capsular bag on the support ring into axial movement of the optic, allowing a presbyopic patient to more effectively focus on near objects. The outer ring is preferably contoured to conform to the portion of the capsular bag between the anterior and posterior zonules, and has sufficient axial thickness to contact both sets of zonules. In addition, the edge of the ring includes at least one sharp edge corner to prevent epithelial cell growth toward the optic. In addition, the outer ring may include weakened areas configured to allow consistent and repeatable deformation in response to compressive forces.
