In an apparatus for ophthalmological, in particular refractive, laser surgery a pachymetric measuring device (34) based on an optical-coherence interferometric measuring process is controlled in such a way that the position of the measuring beam emitted by the measuring device (34) follows movements of the eye (10) to be treated. The eye movements are registered by means of a camera (30) of an eye-tracker. For the purpose of changing the position of the measuring beam, a partially transmitting deflecting mirror (42), via which the measuring beam is routed onto the eye (10), is movably, in particular tiltably, arranged.

L'invention concerne un dispositif de chirurgie laser, notamment réfractive, en ophtalmologie, comportant un dispositif de pachymètrie (34) qui est commandé selon un procédé d'interférométrie optique cohérente, de manière que la position du faisceau de mesure émis par le dispositif de mesure (34) suive les mouvements de l'oeil (10) à traiter. Les mouvements de l'oeil sont suivis par une caméra (30) d'un oculomètre. Pour modifier la position du faisceau de mesure, un miroir de déviation (42) partiellement transparent est disposé mobile notamment basculant, ce miroir dirigeant le faisceau de mesure vers l'oeil (10).
