Accommodating intraocular lens

An accommodating intraocular lens (IOL) comprising:

• a lens;
• a flexible surface;
• an articulating member joining the lens and the flexible surface to form an enclosed cavity, the articulating member comprising first and second rings coupling the lens and the flexible surface, respectively, to a peripheral portion;
• a first hinge disposed between the lens and the first ring;
• and
• a second hinge disposed between the flexible surface and the second ring.

An accommodating intraocular lens (IOL) configured for implantation in a lens capsule of a patient's eye, the IOL comprising:

• a refractive anterior lens;
• a deformable posterior membrane;
• an articulating member joining the refractive anterior lens and the posterior membrane to form an enclosed cavity, the articulating member comprising an anterior portion, a posterior portion, and a peripheral portion;
• the anterior portion having one end coupling the anterior lens and the other end coupling the peripheral portion;
• the posterior portion having one end coupling the posterior membrane and the other end coupling the peripheral portion;
• wherein in a first state, opposing sides of the peripheral portion move toward one another to displace the anterior lens in an anterior direction and causing the radius of curvature of the posterior membrane to increase;
• and
• wherein in a second state, opposing sides of the peripheral portion move away from one another, displacing the anterior lens in a posterior direction causing the radius of curvature of the posterior membrane to decrease.
