  • Publication number: 20250064643
    Abstract: An ophthalmic knife for treatment of various conditions including eye diseases, such as glaucoma, using minimally invasive surgical techniques is provided. The ophthalmic knife includes a shaft, a first platform connected to an end of the shaft and extending at an angle from a longitudinal axis of the shaft and a second platform connected to the shaft adjacent to the first platform. The first platform includes a first top surface extending from a first tip and a first bottom surface opposing the first top surface, and the second platform includes a second top surface extending from a second tip, and a second bottom surface opposing the second top surface. The first platform severs trabecular meshwork in a human eye as the trabecular meshwork advances over the first top surface of the first platform and the second bottom surface of the second platform engages but does not sever the trabecular meshwork.

  • Patent number: 12213920
    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.

    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: 20240207097
    Abstract: An internal mechanism configured to pump a fluid in an ophthalmic device is provided. The internal mechanism includes an inlet port, a drive member coupled to the actuator and a plunger coupled to the drive member. The drive member provides a force that moves the plunger in a first direction when the actuator moves from an un-pressed position to a pressed position, the movement of the plunger in the first direction causing the fluid to move from the inlet port and through a cannula and causing a portion of the fluid to exit one or more orifices of the cannula. An ophthalmic device having an internal mechanism is also provided.
