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.

Abstract: An ophthalmic device includes an optic including an optic axis and an open-loop haptic structure coupled with the optic. The open-loop haptic structure includes a pair of open loops, the pair of open loops comprising a first open loop and a second open loop. At least a portion of the first open loop extends in a first angular direction. At least a portion of the second open loop extends in a second angular direction, the second angular direction being opposite the first angular direction.
