  • Publication number: 20230083797
    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.

  • Publication number: 20220287823
    Abstract: An intraocular lens system may include a base that may include an annular body, an opening extending through the annular body in an axial direction of the annular body, and a recess extending circumferentially about the opening. The system also may include a lens that may be insertable into and removable from the recess. The lens may include a central optic, a first tab protruding radially away from the central optic, and a second tab protruding radially away from the central optic. The second tab may be more resistant to compression in a radial direction than the first tab. The first tab may include a first arm protruding radially away from the central optic, a second arm protruding radially away from the central optic and extending away from the first arm, and a third arm extending from the first arm to the second arm. Movement of one or more of the first, second, and third arms may result in deformation of the first tab.

  • Patent number: 11337797
    Abstract: Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. A device for delivery of the IOL into the eye may include a nozzle; a bay adjacent to the nozzle, wherein the bay is configured to contain the lens component and comprises a recess in a shape of a haptic extension; and a cam-actuated mechanism comprising a slider configured to move in a direction toward the nozzle; a side arm moveably disposed within the bay, wherein the side arm is positioned at an end of the slider, the end of the slider comprising a groove aligned with the side arm, wherein the groove extends from an outer edge of the slider into an interior portion of the slider, wherein the groove is angled to receive the side arm as the slider moves.

  • Publication number: 20210290374
    Abstract: Intraocular lenses (IOLs) that improve lens stability by, for example, increasing anterior-posterior stiffness of the IOL, increasing anterior-posterior dimensions of the IOL and/or increasing contact area with the equator of the bag to resist movement of the IOL as the bag collapses over time. These IOLs may be non-modular (single component) or modular (multiple component). In modular embodiments, the IOL system may include intraocular base and optic components, which, when combined, form a modular IOL.
