An ophthalmic device includes an optic including an optic axis and a periphery and a closed-loop ring haptic structure coupled with the optic. The closed loop haptic structure includes a first ring structure having a first characteristic length, a second ring structure having a second characteristic length, and a plurality of connectors coupling the first ring structure and the second ring structure. The first ring structure is positioned adjacent to the periphery of the optic and is coupled to the entire periphery of the optic, and the first characteristic length is less than the second characteristic length.
