  • Patent number: 11931247
    Abstract: Systems, methods, and apparatuses for storing and/or shipping an intraocular lens (IOL) cartridge are provided. A system comprises the IOL cartridge. The IOL cartridge comprises a nozzle and a compartment comprising an IOL. The nozzle is in fluid communication with the compartment. The IOL cartridge further comprises a dial disposed adjacent to the compartment, wherein an inner surface of the dial is exposed to the compartment. The dial is configured to fold the IOL upon rotation of the dial. The IOL cartridge further comprises a plunger case in fluid communication with the compartment, wherein a plunger is movably disposed within the plunger case. The IOL cartridge is configured to removably attach to a handpiece.

  • Patent number: 11931248
    Abstract: An IOL system includes a capsular ring having a concave exterior surface extending around its circumference that is configured, upon insertion into a capsular bag of a patient's eye, to engage an equatorial region of the capsular bag. The concave exterior surface extends between an anterior surface and a posterior surface of the capsular ring. A first one or more flaps are arranged on the anterior surface such that at least a portion of each of the first one or more flaps, upon insertion into the capsular bag of a patient's eye, engages an anterior portion of the capsular bag. Similarly, a second one or more flaps are arranged on the posterior surface such that at least a portion of each of the second one or more flaps, upon insertion into a capsular bag of a patient's eye, engages a posterior portion of the capsular bag.

  • Patent number: 11911263
    Abstract: Systems, methods, and apparatuses for storing and/or shipping an intraocular lens (IOL) cartridge are provided. A system comprises a packaging comprising a passage. The IOL cartridge is removably disposed within the passage. The IOL cartridge comprises a nozzle and a compartment configured to receive an IOL. The nozzle is in fluid communication with the compartment. The IOL cartridge further comprises a dial configured to rotate upon withdrawal of the IOL cartridge from the passage, wherein an inner surface of the dial is exposed to the compartment. The dial is configured to fold the IOL and release the IOL cartridge from the packaging upon rotation of the dial.

  • Patent number: 9931202
    Abstract: An IOL includes a fluid optic body having a cavity defined by a sidewall, a deformable optical membrane intersecting the sidewall around an anterior circumference of the sidewall, and a posterior optic intersecting the sidewall around a posterior circumference of the sidewall. The posterior optic includes a central protrusion extending anteriorly into the cavity and the deformable optical membrane includes a ring-shaped protrusion extending posteriorly into a space between the sidewall and the central protrusion. A second optic body is spaced apart from the fluid optic body and coupled thereto via a plurality of struts. Axial compression causes the plurality of struts to deform the sidewall in a manner that increases the diameter of the cavity, modifying a curvature of the deformable optical membrane is modified. Contact between the ring-shaped protrusion and the central protrusion defines a maximum modification to the curvature of the deformable optical membrane.
