    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.

    IPC: A61F2/16

    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.

    IPC: A61F2/16

    Abstract: An intraocular lens (IOL) injectors and associated methods are described. The IOL injectors may include a collapsible portion configured to reduce the length of the IOL injector when the collapsible portion is altered from an uncollapsed configuration to a collapsed configuration. In some instances, an IOL may be advanced from a storage location to a dwell location when the collapsible portion is altered from the uncollapsed configuration to the collapsed configuration. The IOL injectors may also include a combination push and screw drive.

    Abstract: An ophthalmic device includes an optic and a haptic structure coupled with the optic. The optic includes an optic axis. The haptic structure is coupled to the optic. The haptic structure retains the ophthalmic device within a capsular bag of a patient's eye. At least a portion of the haptic structure has a cross-section and a peripheral surface forming an outer periphery of a portion of the cross-section. At least a portion of the peripheral surface contacts the capsular bag and is smoothly curved.
