In certain embodiments, a system for tracking movement of an eye comprises a camera system, a computer system, and an output device. The camera system generates images of the eye. The computer system stores the images and at least one of the images as a reference image. The computer system also tracks movement of the eye within a tracking range by comparing a current image with the reference image, and by determining a movement of the eye from the comparison of the current image and the reference image. The tracking range has one or more alert points. The computer system also determines an orientation of the eye relative to at least one alert point of the tracking range. The output device outputs a range indicator that indicates the orientation of the eye relative to the at least one alert point of the tracking range.

Tracking movement of an eye within a tracking range

The present disclosure generally relates to a method for controlling a medical device. The method may comprise tracking movement of a foot with a hands-free device and processing movement of the foot to move a cursor, wherein the cursor is disposed on a display screen of the medical device. The method may further comprise receiving a selection of at least one icon with the cursor through the hands-free device. A system for controlling a medical device may comprise a console and a display screen coupled to the console and may be configured to display a cursor. The system may further comprise a hands-free device. The hands-free device may be communicatively coupled to the console and may be operable to track movement within a tracking area and generate an output. The system may further comprise a medical device connected to the console and a processor configured to execute instructions.

Foot controlled cursor

A method and system are described that allow a user to verify a registration proposal during an image-guided 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.

Shaking image for registration verification

A multi-beam splitter enables superimposing overlay content onto an optical field of view of a microscope using a compact and flexible design that is cost-effective for many applications. The multi-beam splitter also enables capturing of the optical field of view without the overlay content.
