Abstract
A device for ophthalmologically treating the eye has a treatment laser beam (UV) for ablating parts of the cornea (12) and a fixation light beam (24). A fixation light spot in the vicinity of the fovea (30) and the fovea are imaged by means of a camera (40). This makes it possible to check whether the patient has reliably fixated the fixation light source (22). In addition, the pupil can be recorded and both recordings can be superimposed.
