  • Publication number: 20220168093
    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.

  • Patent number: 11103343
    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.

  • Publication number: 20210121286
    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.

  • Publication number: 20190183638
    Abstract: A method for performing an ophthalmic procedure on an eye, the eye having a capsular bag in which an intraocular lens (IOL) has been implanted, includes applying energy to a portion of the capsular bag. The applied energy is sufficient to melt the portion of the capsular bag without cauterization such that the portion of the capsular bag adheres to an adjacent portion of the IOL.
