  • Patent number: 10010447
    Abstract: A retinal treatment system for delivering therapeutic agents to a target location with a retina is disclosed herein. The retinal treatment system includes a console having a control system and a handheld device coupled to the control system. The handheld device includes an inner tube disposed within an outer tube and being axially moveable within the outer tube. The inner tube has a perforating tip that is configured to perforate an inner limiting membrane of the retina. The handheld device further includes a chamber coupled to a proximal end of the inner tube that is configured to receive a fluid containing therapeutic agents injectable from the perforating tip. The control system of the retinal treatment system permits a user to maintain a position of the handheld device relative to the retina and activate an injection of a portion of the fluid through the inner tube into the retina.

  • Patent number: 9844314
    Abstract: An ophthalmic surgical microscope can include a movable optical element positioned in an optical pathway of light reflected from a surgical field. The movable optical element can be configured to oscillate in a direction along the optical pathway. The microscope can include an actuator coupled to the movable optical element and configured to move in response to a control signal. The microscope can include a computing device in communication with the actuator and configured to generate the control signal to move the movable optical element. In some embodiments, the computing device is configured to generate the control signal to move the movable optical element with an oscillation frequency greater than the critical flicker fusion rate.

  • Patent number: 9730576
    Abstract: An endoilluminator system includes an endoilluminator probe and an illumination source. The endoilluminator probe includes a nano-scale optical fiber and a probe fiber connector, and the illumination source includes a source fiber connector. The illumination source is configured to produce an illumination spot at the source fiber connector having a diameter smaller than a diameter of a fiber core of the nano-scale optical fiber. The probe fiber connector and the source connector are configured when connected to align the illumination spot off-center relative to the nano-scale optical fiber such that the angular distribution of light emitted by the nano-scale optical fiber is increased relative to aligning the illumination spot at a center of the nano-scale optical fiber.

  • Patent number: 9693686
    Abstract: Systems, apparatuses, and methods of and for an ophthalmic visualization system are disclosed. An example ophthalmic visualization system may include a first lens positioned relative to a surgical microscope in a manner facilitating viewing of a central region of a retina through the surgical microscope during a surgical procedure. The first lens may be positionable in an optical path between an eye and the surgical microscope during the surgical procedure. The example ophthalmic visualization system may also include a second lens selectively positionable relative to the surgical microscope and the first lens in a manner facilitating viewing of a peripheral region of the retina of the eye during the surgical procedure. The second lens may be selectively positionable in the optical path such that the peripheral region is selectively viewable without changing the position of the first lens during the surgical procedure.
