Abstract: An ophthalmic surgical system can include a light source configured to generate a light beam and a filter wheel disposed between the light source and an intraocular illumination device. The filter wheel can include an unfiltered area, a first filtered area, and a second filtered area. The first and second filtered areas can limit transmission of certain wavelengths of the light beam to the intraocular illumination device. The system can include an actuator configured to selectively move the filter wheel to cause the light beam to pass through the unfiltered area, the first filtered area, and/or the second filtered area. The system can include a computing device configured to provide a control signal to the actuator. The computing device can be configured to provide a control signal to the actuator based on a beam location, a beam composition, an exposure time, and/or a limited visibility condition.

Abstract: Various embodiments are generally directed to a surgical instrument for detecting light, such as by measuring light traveling in a waveguide, for instance. Some embodiments are particularly directed to a determining one or more parameters associated with ocular surgery based on detection of the light. In one or more embodiments, for example, a surgical instrument may include a cannula, a waveguide, a transducer, and logic implemented in circuitry communicatively coupled with the transducer. In one or more such embodiments, the cannula may comprise at least a portion of the waveguide. In some embodiments, the transducer may detect light traveling in a first direction in the waveguide. In some such embodiments, the logic may determine at least one parameter associated with ocular surgery based on the light detected by the transducer.

Abstract: Vitreoretinal instruments and methods related thereto are disclosed herein. The disclosure describes various example vitreoretinal instruments having various aspirating port configurations. A vitreoretinal instrument may include a handle and a cannula coupled to the handle. The cannula may include a straight portion and a curved portion. The curved portion may be configurable between a straight configuration and a curved configuration. The curved configuration may include a first curved portion having a curvature defined by a first radius. The curved configuration may include a second curved portion having a curvature defined by a second radius different from the first radius. The curved portion may further include one or more ports formed in the curved portion.

Abstract: This disclosure relates to a tissue separation system to separate the posterior vitreous cortex from the inner limiting membrane in the eye, and to the separation of other body tissues. A system includes a flexible elongate member having a proximal end and a distal end. The flexible elongate member is coupled to a fluid reservoir and has a lumen configured to deliver fluid from the reservoir for use in a surgical procedure and further includes a pump system coupled to the proximal end of the flexible elongate member and to the fluid reservoir, configured to pressurize the fluid to a pressure suitable for separating tissues. The system also includes a control system arranged to control the pump system to provide a series of pulses of fluid through the flexible elongate member and out from the distal end thereof to suitably separate the tissues during the surgical procedure.

Abstract: Methods, systems, and software for controlling infusion pressure, such as during a medical procedure, using systemic blood pressure are described. Systemic blood pressure, such as brachial arm blood pressure or radial artery blood pressure, may be used to estimate central retinal artery blood pressure to estimate critical closing pressure. Further, the disclosure relates to controlling infusion pressure to prevent an increase in intraocular pressure above the estimated critical closing pressure when such is not desired, and, when such is desired, using systemic blood pressure and infusion pressure to control an intentional increase in intraocular pressure above the estimated critical closing pressure to stop intraocular bleeding.

Abstract: Active noise cancellation is employed to address unwanted acoustical noise generated by various equipment associated with an ophthalmic surgical system. Active noise cancellation may be used within a chassis of the ophthalmic surgical system, within an air compressor used with the ophthalmic surgical system, and within a reciprocating surgical probe used with the ophthalmic surgical system.

Abstract: An ophthalmic illumination system includes a light source generating a source light beam and a beam splitter splitting the source light beam into first and second light beams. A first attenuator is located in a path of the first light beam and a second attenuator is located in the path of the second light beam, the first and second attenuators operable to change the intensities of the first and second light beams, respectively. A first optical fiber port is configured for connection to a first optical fiber for delivering the first light beam to a patient's eye and a second optical fiber port is configured for connection to a second optical fiber for delivering the second light beam to the patient's eye. A control unit is communicatively coupled to the first and second attenuators and is operable to adjust the attenuators to control the intensities of the light beams delivered to the patient's eye.

Abstract: The present disclosure describes systems and methods for pressure-driven micro-surgical tool actuation. The systems and methods may encompass the use of a remote handle held by a first hand of a user as well as a surgical tool located in the eye of a patient. A primary actuator may be included in remote handle and operable to be actuated by a mechanical force exerted on the handle. Actuating the primary actuator pressurizes a fluid within a length of tubing. The pressurized fluid may be transmitted to a dynamic tool held by a second hand of the user, where the pressurized fluid may be used to actuate a subordinate actuator. Actuation of the subordinate actuator may actuate a dynamic component of the dynamic tool.
