Abstract:
1. An implantable intraocular lens for placement within an eye having a capsular bag connected to a ciliary muscle via zonules, comprising: an optic comprising a material, and disposed about an optical axis and including an anterior surface and a posterior surface, the optic configured to be biased to be in an un-accommodated state in the absence of any force; a positioning member operably coupled with the optic and responsive to relaxation of zonules within an eye in order to change the shape of the optic from a first optic shape to a second optic shape, where the second optic shape has a thickness that is greater than the first optic shape, the second optic shape corresponding to an accommodated state; the positioning member comprising a plurality of spaced-apart positioning legs which are arcuate when viewed in a cross section along a plane containing the optical axis, wherein the positioning legs are connected to each other by an annular segment positioned anterior or posterior of the optic; and a plurality of haptic arms integrally formed with the plurality of positioning legs and extending from the plurality of positioning legs toward the optic, wherein the haptic arms are coupled to the optic; wherein accommodation in response to a relaxation of the zonules is achieved when the optic changes from the first shape to the second shape.
