Abstract: An ophthalmic lens includes an optic comprising an anterior surface, a posterior surface, and an optic edge extending between the anterior surface and the posterior surface, the optic having an optical axis. The ophthalmic lens further includes a plurality of haptics extending from a periphery of the optic, each of the plurality of haptics including a gusset region, a distal region, and an elbow region connecting the gusset region to the distal region. The gusset region of each of the plurality of haptics extends from the periphery of the optic and spans a portion of the periphery of the optic. In addition, the gusset region of each of the plurality of haptics monotonically increases in thickness with increased distance from the periphery of the optic, while the distal region of each of the plurality of haptics monotonically decreases in thickness with increased distance from the elbow region.

Abstract: An ophthalmic device includes an optic having an optic axis and a closed-loop haptic structure coupled with the optic. The closed loop haptic structure includes a first hinge having a first section, a second section, and a connecting section extending between the first section and the second section. The first section has a first component extending in a first angular direction and a second component extending in a second angular direction that is opposite to the first angular direction. The closed loop haptic structure further includes a second hinge including a radial section and an axial section extending from the axial section in the first angular direction, the radial section having a cross-sectional area greater than a maximum cross-sectional area of the first hinge.

Abstract: Polymeric eye inserts are provided that may be dissolvable when placed in the cul-de-sac of the eye. These inserts may contain one or more polymers as well as a softener/plasticizer so that, when inserted into the eye, they may absorb tears, and dissolve and slowly release lubricant into the tear film to lubricate and protect the ocular surface for an extended duration of time. Increased retention time on the ocular surface for longer lasting relief may reduce dosing frequency and patient burden typically associated with topical drop usage. These polymeric eye inserts also may include one or more pharmaceutically active agents.

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 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.

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.
