    Abstract: Ophthalmic surgical devices, systems, and methods for regulating aspiration from a patient's eye are provided. A vacuum pump in fluid communication with an aspiration line provides fluid aspiration from a vitreous chamber of the eye through the aspiration line. A sensor disposed adjacent to or inside the eye determines sensor data relating to an intraocular pressure (IOP). The controller receives the sensor data and regulates the aspiration in response to changes in the TOP, such as by controlling the vacuum pump. The controller may determine whether a fluid infusion to the vitreous chamber through an infusion line is below a maximum infusion level, regulate the infusion in response to the TOP being below a threshold value and the infusion being below the maximum infusion level, and regulate the aspiration in response to the TOP being below the threshold value and the infusion being at or above the maximum infusion level.

    Abstract: Devices, systems, and methods for glare reduction in surgical microscopy are provided. A method of operating a surgical microscope may include: receiving light reflected from the surgical field at an image sensor; processing the received light to generate image data; identifying portions of the image data representative of glare; and controlling an optical element to limit the transmission of light associated with the glare. A surgical microscope may include: an image sensor configured to receive light reflected from the surgical field, a computing device, and an optical element. The computing device may be configured to: identify portions of the light received at the image sensor associated with glare and generate a control signal to limit the transmission of the light associated with the glare. The optical element may be configured to selectively limit the transmission of the light associated with the glare in response to the control signal.

    Abstract: A vitrectomy surgical system is disclosed herein. The surgical system includes a vitrectomy probe having a cutting portion comprising an inner cutting tube, an outer cutting tube, and an outer port. The inner cutting tube is movable relative to the outer cutting tube to cut vitreous humor during a vitrectomy procedure. The surgical system further includes a motor configured to move the inner cutting tube relative to the outer cutting tube and one or more pressure sensors coupled to the vitrectomy probe to measure a pressure proximate to a distal portion of the vitrectomy probe and provide pressure feedback. Related systems and methods are also included.

    Abstract: Ophthalmic surgical devices, systems, and methods for automatically controlling the injection or extraction of viscous fluids from a patient's eye are provided. A syringe pump connected with an actuation line and a powered syringe provides pressures for viscous fluid injection or extraction in a vitreous chamber of the eye. A sensor disposed adjacent to or inside the eye determines sensor data relating to an intraocular pressure (IOP). The controller receives the sensor data and regulates the injection or extraction of the viscous fluid in response to the detected IOP, such as by controlling the syringe pump. The controller may determine whether the IOP is above an upper threshold or below a lower threshold and may control the syringe pump to regulate the injection or extraction of viscous fluid to maintain the IOP between the upper and the lower thresholds.
