Abstract
An ophthalmic surgical system comprises a surgical microscope that provides a field of view of a surgical site to a user. A microscope display device displays a graphical overlay and the field of view. The graphical overlay displays fields to adjust configurable settings that modify operation of a surgical instrument. A footswitch receives user input from the user to adjust the configurable settings by: detecting a first movement of a joystick by the user, the first movement representing movement of a cursor relative to the fields; and detecting a second movement of the joystick or a button by the user, the second movement representing a selection of a field. The computer: generates a control signal to adjust the configurable settings in the response to the user input; and outputs the control signal to the surgical instrument to adjust the configurable settings according to the user input.
