Abstract:
An intraocular lens comprising:an optic structured to focus light onto a retina of an eye and having an optical axis; and a movement assembly sized and structured to cooperate with the eye to effect accommodating movement of the optic and including: a suspension structure sized and structured to be in contact with a peripheral region of a capsular bag of the eye, the suspension structure including a plurality of arcuate contact plates; and a plurality of movement members coupled to the optic and to the suspension structure, each of the plurality of movement members including a first segment and a second segment, the first segment having a distal end pivotally coupled to a respective one of the contact plates at a location and a proximal end, the second segment having a distal end pivotally coupled to the proximal end of the first segment at a first pivot point and a proximal end pivotally coupled to a periphery of the optic at a second pivot point; wherein the movement members are sized and structured to convert and amplify radial movement of the suspension structure caused by movement of the capsular bag to axial movement of the optic, and wherein none of the movement members extend beyond a repective plane defined by a central optical axis of the optic and perpendicular to a radially extending line from the optical axis to the respective location.
