Abstract: A method and system provide an ophthalmic device including an optic and a haptic. The optic includes at least one optical material having a first Young's modulus. The haptic is coupled with the optic. The haptic includes at least a second Young's modulus greater than the first Young's modulus and less than 1.8 GPa. Thus, the haptic is stiffer than the optic, but more flexible than a material such as polymethyl metacrylate (PMMA).

Abstract: An ophthalmic device includes an optic including an optic axis and a closed-loop haptic structure coupled to the optic via a frame surrounding the optic, the closed-loop haptic structure including a closed loop extending from first and second attachment points to the frame. The closed loop includes a first hinge and a second hinge. The first hinge has a first section having a first component extending in a first angular direction, a second section having a second component extending in a second angular direction opposite to the first angular direction, and a first connecting section between the first section and the second section. The second hinge has a third section having a third component extending in the second angular direction, a fourth section having a fourth component extending in the first angular direction, the fourth section being connected to the second section to form the closed loop.
