Abstract
The invention concerns a microscope, in particular an operating microscope with an autofocussing system that adjusts focus based on the user's gaze. A sensor tracks pupil position and this information is evaluated to determine a specific area in the user's field of vision to which the user's gaze is directed, and the autofocussing system brings the specific area into focus.
