Abstract
An accommodating intraocular lens (IOL) comprises an anterior lens, a posterior surface and an articulating member joining the anterior lens and the posterior surface to define an enclosed cavity. The articulating member comprises anterior and posterior arms coupling the anterior lens and the posterior surface, respectively. The articulating member further comprising a peripheral portion. A posterior flex region is disposed about the posterior arm and at a distance from the peripheral portion. The posterior flex region permits the flexible posterior surface to articulate relative to the posterior arm, to decrease the radius of curvature of the posterior surface as the peripheral portions on opposing sides of the IOL move toward one another in a first state and to increase the radius of curvature of the posterior surface as the peripheral portions on opposite sides of the IOL move away from one another in a second state.
