  • 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.

  • Patent number: 11110008
    Abstract: A microsurgical device and methods of its use can be used for treatment of various conditions including eye diseases, such as glaucoma, using minimally invasive surgical techniques. A dual-blade device can be used for cutting the trabecular meshwork (“TM”) in the eye. The device tip provides entry into the Schlemm's canal via its size (i.e., for example, 0.2-0.3 mm width) and configuration where a ramp elevates the TM away from the outer wall of the Schlemm's canal and guides the TM to first and second lateral elements for creating first and second incisions through the TM. The dimensions and configuration of the blade is such that an entire strip of TM is removed without leaving TM leaflets behind and without causing collateral damage to adjacent tissues.

  • Publication number: 20210267751
    Abstract: An intraocular drug delivery platform for use with an intraocular lens assembly. The platform includes a ring and haptics to maintain the ring in position in the capsular bag, compartments on the anterior surface of the ring for accommodating a drug eluting matrix or other drug mass, and a skirt extending posteriorly from the posterior surface of the ring to constrain movement, including lateral or inferior/superior movement, of the intraocular lens relative to the ring.

  • Patent number: 10945883
    Abstract: Intraocular drainage devices, intraocular implantation procedures, and inserter devices for intraocular implantation procedures are disclosure. A disclosed intraocular drainage device includes a tube having a distal end and a body disposed proximal to the tube. An inlet port is disposed on the distal end of the tube and configured to receive an influent fluid from an anterior chamber of an eye. An inlet fluid pathway is coupled to the inlet port and extends at least partially through the tube. A plurality of outlet fluid pathways extend at least partially through the body and branch from the inlet fluid pathway. A plurality of outlet ports are disposed on the body and coupled to the plurality of outlet fluid pathways. A disclosed inserter device for an ocular implantation procedure includes a handle, a needle, and a plunger. The needle is disposed on a distal end of the handle and configured to hold an intraocular drainage device. The plunger is coupled to the needle and disposed in the handle.

  • Patent number: 10940109
    Abstract: The disclosure relates to multilayer polymeric matrix based medical devices. In one example, a device comprises an inner first polymeric matrix and an outer second polymeric matrix. The addition of second polymeric matrix modifies bulk properties of each matrix thus resulting in a device where specific bulk properties are incorporated. The disclosure also relates to methods of manufacturing various embodiments of medical devices and their uses.

  • Publication number: 20200360186
    Abstract: An ophthalmic device including a cannula having a cannula distal end, a lumen, and one or more orifices coupled to the lumen is provided. The cannula is configured to deliver a fluid. A sleeve is disposed around the cannula and has a sleeve distal end. A handle is coupled to the sleeve and the cannula, the handle having an actuator. An internal mechanism is coupled to the actuator and configured to retract the sleeve relative to the cannula. The internal mechanism includes a follower fixedly coupled to the sleeve and moveable between distal and proximal positions, and a release member movable between an activated position and a release position. The release member is coupled to the actuator and configured to release a force that urges the follower from the distal position to the proximal position when the release member moves from the activated position to the release position.

  • Patent number: 10736735
    Abstract: The present invention relates generally to the fields of ophthalmology and cataract surgery. More specifically, the present invention relates to a device implanted in the eye during cataract surgery and improves the optical functionality of the eye. This invention is in the field of medical devices and relates to capsular tension rings that are designed to be implanted in the capsular sac after removal of the crystalline lens affected by a cataract in association with an intraocular lens designed to replace the crystalline lens. The invention applies to stabilizing the artificial lens from movement in the x-y-z planes and prevents rotation.
