Abstract: The present disclosure provides an intraocular lens (IOL) or ophthalmic device including an optic and at least one haptic, at least a portion of which is formed from a photoresponsive shape memory polymer network, such as a polydomain azo liquid crystalline polymer network (PD-LCN). The present disclosure further provides systems and methods for adjusting the position of such an IOL or other ophthalmic device using polarized laser radiation.

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 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 intraocular lens includes an optic having an anterior optic surface, a posterior optic surface, and an optic edge extending between the anterior optic surface and a posterior optic surface. The optic edge includes a convex portion extending from a periphery of the anterior optic surface and a flat portion extending from a periphery of the posterior optic surface such that a corner edge is formed between the optic edge and the posterior optic surface. The flat portion intersecting the convex portion to form the optic edge. Such an optic edge may eliminate glare or other undesired effects that adversely impact quality of vision.

Abstract: The present disclosure provides an intralocular-lens (IOL) or ophthalmic device including an optic and at least one haptic, at least a portion of which is formed from a photoresponsive shape memory polymer network, such as a polydomain azo liquid crystalline polymer network (PD-LCN). The present disclosure further provides systems and methods for adjusting the position of such an IOL or other ophthalmic device using polarized laser radiation.

Abstract: An exemplary ophthalmic lens includes an optic comprising an anterior optic surface and a posterior optic, and a multi-curvature optical edge surrounding the optic and connecting the anterior optic surface to the posterior optic surface, the multi-curvature optical edge comprising a plurality of tangentially-connected curved surfaces configured to mitigate positive dysphotopsia by directing or diffusing from light incident on the multi-curvature optical edge away from a fovea of a patient.

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.
