An instrument is proposed for examining a human eye, with an eye-tracker foracquiring eye movements and for outputting a signal that is representative oftheacquired eye movements, the eye-tracker including an interferometricimage-acquisition device that has been set up for time-resolved aquisition ofsectionalimages of the eye and that operates on the basis of two-dimensional or three-dimensionaloptical coherence tomography, and also an evaluation moduleascertaining the eye movements solely from the sectional images.
