Abstract: A modular intraocular lens (IOL) with a ring configured to prevent glare artifacts. The ring includes a flange on the posterior rim, in which an anterior surface on the flange has a first profile and a posterior surface of the flange has a second profile non-parallel with the first profile. Non-parallel surfaces of the flange can be configured to defocus light transmitted at off-axis angles through an optic and the flange.

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 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.
