  • Patent number: 11779457
    Abstract: Embodiments disclosed herein relate to systems and methods for securing a drug delivery component to an intraocular lens (IOL) assembly. The systems generally include a support base and a plunger. The support base includes a first portion configured to accommodate a drug delivery component; and a second portion configured to act as a plunger guide. The plunger can be inserted into the plunger guide such that the plunger is positioned to interface with a drug delivery component and an IOL assembly during use. The plunger includes an elongated body and a tip, wherein the tip can include a ramp configured to interface with a fixation loop of a drug delivery component during use and a compartment configured to interface with a haptic of an IOL assembly during use.

  • Patent number: 11771592
    Abstract: Embodiments disclosed herein generally relate to a stabilized intraocular drug delivery system for implantation into an eye of a subject. The system can include an intraocular lens (IOL) assembly and a drug delivery component. The IOL assembly can include a lens and a haptic. The haptic can include an outer end, an inner end opposite the outer end, a retention tab at the inner end, and a connection tab positioned between the outer end and the inner end and adjoining the lens. The drug delivery component can include at least one therapeutic agent and a fixation portion having an opening to receive the haptic and secure the drug delivery component to the IOL assembly. The fixation portion of the drug delivery component can be secured to the connection tab of the haptic such that the retention tab inhibits movement of the drug delivery component relative to the IOL assembly.

  • Publication number: 20230301832
    Abstract: Ophthalmic devices include a housing and a cannula extending from the housing, the cannula having a lumen for fluid flow, a reservoir for holding fluid and an activation assembly. The activation assembly includes a rotatable wheel and a moveable housing ring coupled to the wheel, the coupled rotatable wheel and moveable housing ring configured to move inward together towards an interior of the housing when an inward force is applied to the wheel and to move outward together away from the interior of the housing when an outward force is applied to the coupled wheel and the moveable housing ring. Methods of operating ophthalmic devices are also provided.

  • Patent number: 11759356
    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.

  • Publication number: 20230105856
    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 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 device 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: 20220370195
    Abstract: Modular IOL removal systems and methods that cut an optic portion of an intraocular in a single motion such to facilitate removal of the optic portion from an eye through an incision, for example a corneal incision, without increasing the size of the corneal incision. Various cutting tools having one or more blades may be utilized. The cut intraocular lens may have one continuous cut or be cut into multiple smaller pieces. The single cutting step may apply balanced forces and torque to avoid damaging the surrounding eye anatomy, reducing the risk of trauma.

  • Publication number: 20220354696
    Abstract: Apparatus and methods for ocular treatment are provided. The apparatus can comprise an outer sheath and a microcannula movably housed within the outer sheath and having a proximal end, a distal end, a cavity, and a central longitudinal axis. The apparatus can include a first protrusion extending circumferentially inward at a distal end of the outer sheath and a second protrusion located on an outer circumferential surface of the microcannula. The apparatus can include multiple orifices disposed on the microcannula distal end, each of the orifices defining a channel extending transverse to the central longitudinal axis and configured to deliver a substance radially outwardly from the distal tip of the microcannula. The distal tip can extend out from a distal opening of the outer sheath when the microcannula is in an extended position and can be housed within the outer sheath when the microcannula is in a retracted position.

  • Publication number: 20220346943
    Abstract: A modular IOL system including intraocular primary and secondary components, which, when combined, form an intraocular optical correction device, wherein the secondary component is placed on the primary component within the perimeter of the capsulorhexis, thus avoiding the need to touch or otherwise manipulate the capsular bag. The secondary component may be manipulated, removed, and/or exchanged for a different secondary component for correction or modification of the optical result, on an intra-operative or post-operative basis, without the need to remove the primary component and without the need to manipulate the capsular bag. The primary component may have haptics extending therefrom for centration in the capsular bag, and the secondary component may exclude haptics, relying instead on attachment to the primary component for stability. Such attachment may include actuatable interlocking members.
