Abstract: A method and system are described for automatically centering in an XY plane a field of view of a patient's eye under high magnification during ophthalmic surgery. The method includes automatically moving the center of the field of view to the center of a circular image detected in a real-time video signal acquired from the field of view of the patient's eye under high magnification during ophthalmic surgery. The system configured to perform the method has a processor and a non-transitory computer-readable medium accessible to the processor containing instructions executable by the processor to perform the method.

Abstract: Certain embodiments provide a vitrectomy probe including a housing, an actuator disposed inside the housing, a cutter coupled to the actuator and extending from the housing and an air turbine disposed inside the housing. The air turbine includes a rotor and a plurality of turbine blades coupled to the rotor. The vitrectomy probe includes a valve body interfacing with the rotor. During rotation of the air turbine, air is selectively routed to and from the actuator according to a rotational position of the rotor in relation to the valve body, thereby reciprocating the cutter.

Abstract: Embodiments disclosed herein provide devices, systems, and methods for reducing intraocular pressure. For example, the disclosed devices, systems, and methods are useful for reducing intraocular pressure resulting from conditions, such as acute glaucoma, on a short-term basis until a definitive surgical procedure is performed. More particularly, valved trocar cannula systems for reducing intraocular pressure resulting from conditions, such as acute glaucoma, pending surgical intervention in an operating room are disclosed. In practice, a trocar assembly is used to place a valved cannula assembly in a patient's eye, such as in the anterior chamber or pars plana, to reduce high intraocular pressure. The valved cannula is then left in the patient's eye for a period of time to continuously allow aqueous humor or liquid vitreous humor to flow therethrough, until the patient may be surgically treated in an operating room.

Abstract: Certain embodiments provide a cannula system with a retention mechanism comprising a cannula, a hub coupled to the cannula, wherein a distal end of the cannula is configured to be inserted into a body part up to the hub, and a retention mechanism configured to create resistance for retaining the cannula inside the body part in response to force exerted on the cannula for pulling the cannula out of the body part. The retention mechanism may include retention elements coupled to a bottom surface of the hub, and by rotating the hub in a first direction, the one or more retention elements that are parallel to a surface of the body part are configured to penetrate the body part. In other embodiments, the retention mechanism may include halfpipe elements that pivot on fulcrum points to hold or release the hub and cannula from the body part.

Abstract: In certain embodiments, an ophthalmic procedure contact lens for ophthalmic treatment of an eye with a laser beam includes a frame, an objective lens, and an illumination ring. The frame has an eye end, an operator end, and a flange-like shape with an interior region. The eye end is configured to be disposed outwardly from the eye. The objective lens is disposed within the interior region of the frame. The objective lens transmits the laser beam through the eye end to treat the eye. The illumination ring is coupled to the frame and provides annular illumination through the eye end to illuminate the eye. The illumination ring includes a ring substrate and light emitters coupled to the ring substrate. The light emitters emit light.

Abstract: A foot pedal device configured to provide force feedback to an operator during ophthalmic surgery is described. The foot pedal device includes a processor and a memory containing instructions which, when executed by the processor, cause the processor to transmit, in response to a movement of a moveable member, a control signal to a surgical console for initiating an action of an ophthalmic surgery tool coupled with the surgical console. The foot pedal device includes a force feedback mechanism configured to selectively apply a resistance force in opposition to the movement of the movable member. The memory contains instructions which, when executed by the processor, cause the processor to receive, from the surgical console, a trigger signal, and send a force feedback signal to the force feedback mechanism. The force feedback mechanism is configured to apply the resistance force to the movable member upon receiving the force feedback signal.

Abstract: Certain embodiments provide an adjustable length infusion cannula having a cannula including a first proximal end and a first distal end, and a hub having a second proximal end, a second distal end, and a central aperture that extends between the second proximal end and the second distal end. The central aperture is configured to accept the first distal end of the cannula and allow the cannula upward movement and downward movement through the hub. The adjustable length infusion cannula also includes a locking mechanism configured to lock the cannula within the hub such that the first distal end extends a first distance past the second distal end of the hub.

Abstract: Embodiments of the present disclosure generally relate to microsurgical cutting devices for ophthalmic procedures. In certain embodiments, a cutting tool assembly includes a first blade in a fixed position and a second blade configured to move relative to the first blade to perform a cutting motion. The first blade includes a first longitudinal body portion and a first end portion extending laterally from the first body portion. A distal surface of the first end portion has a bowed morphology to match a curvature of a retinal surface and is further coated with a first coating to reduce damage to ocular tissues during use. The second blade includes a second longitudinal body portion and a second end portion extending laterally from the second body portion. A distal surface of the second end portion includes a cutting edge for cutting tissues, while a proximal surface thereof is coated with a second coating.

Abstract: The present disclosure relates to high dexterity robotic manipulation systems for ophthalmic microsurgical procedures. In certain embodiments, a robotic surgical system includes a master apparatus controllably coupled to a slave apparatus. The slave apparatus mounts to a patient's head and includes a dual tripod structure having two pluralities of linear actuator links pivotally supporting a surgical tool. The motions of the actuator links are controlled by direct drive actuators to provide at least 6-DOF for the surgical tool. A passive articulating arm having a SCARA mechanism and four-bar parallelogram mechanism attaches to the slave apparatus and counterbalances the weight thereof when mounted on a patient. The surgical system also includes sensors communicatively coupled to the slave apparatus and master apparatus to enable force feedback and force control. Accordingly, the robotic surgical system enhances the dexterity of an operator and enables performance of medical procedures more easily than by hand.
