Abstract: An electronic control unit (ECU) for a digital optical system includes a processor, a non-transitory computer-readable storage medium, and a translation engine. The performance settings include a focus-of-interest setting. Execution of the instructions by the processor causes the processor to receive voice commands from a user via a microphone during an ophthalmic procedure performed using the digital optical system. The voice commands are processed through the translation engine to convert the voice commands into a machine-readable instruction set. The processor adjusts the performance settings using the instruction set to change a state of the digital optical system, including transmitting display control signals to the display screen to overlay a reference grid onto a displayed digital image of a patient's eye. The focus-of-interest setting corresponds to a user-selected grid area of the reference grid.

Abstract: Methods and devices are provided for repairing a tear in a meniscus. A pair of fixation member each entailing a preformed knot configuration coupled together by a suture length. The fixation members are placed on the meniscal tissue with the suture length spanning the tear, the knot configurations are expanded to form anchoring knots and the suture length is shortened to close the tear.

Abstract: The present disclosure generally relates to optical systems for surgical procedures, and more particularly, to optical relay systems for visualization systems used during ophthalmic microsurgical procedures. The optical systems described herein provide improved ergonomics for surgeons, as such systems facilitate a low-height microscope camera that enables a surgeon to see over the camera to a display screen or other monitor placed in an ergonomically advantageous position for ophthalmic procedures. Such optical systems also provide improved performance, as the total magnification of the optical head may be split between multiple lens barrels, thereby creating high resolution images that enables surgeons to see ophthalmic anatomies more clearly. Even further, such optical systems proffer improved manufacturability, with reduced weight and manufacturing cost, as the lens barrels may have fixed focal lengths for utilization with digital magnification mechanisms.
