Abstract
An optical system for eye surgery, comprising at least a surgical microscope, an illumination unit for emitting illumination light, and a control unit. The surgical microscope is configured to output an observation mode signal indicating the employed observation mode and a mode-of-operation signal indicating the employed mode of operation, and the control unit is configured to receive the observation mode signal and the mode-of-operation signal from the surgical microscope and to output a change signal which prompts a change in the amount of light received by the at least one digital image sensor. The change signal is output only if the received observation mode signal and the received mode-of-operation signal indicate a predetermined combination of observation mode and mode of operation.
