1. An intraocular lens (IOL), comprising:
an optic including an optic axis;
a closed-loop haptic coupled to the optic and extending substantially along a first plane perpendicular to the optic axis, the closed-loop haptic comprising:
a first hinge at a first attachment point to the optic, the first hinge comprising a meandering configuration; and
a second hinge at a second attachment point to the optic;
wherein the first hinge and the second hinge are sized and configured to compress such that the closed-loop haptic is substantially compressed inwardly towards the optic axis while remaining substantially in the first plane perpendicular to the optic axis during compression; and
a frame surrounding the optic, and wherein the closed-loop haptic is coupled to the optic at the first attachment point and the second attachment point via the frame,
wherein the optic is positioned in a second plane substantially perpendicular to the optic axis, and wherein the second plane is located posterior to the first plane,
wherein the intraocular lens is configured such that the entire optic substantially remains extending along the second plane during compression of the first hinge and the second hinge,
wherein the first attachment point extends radially and orthogonally from the frame.
