Abstract:
1. Apparatus for treating an eye with laser radiation, exhibiting the following: a laser radiation source for generating laser radiation, focusing optics for directing the laser radiation onto the eye for the purpose of an ophthalmological intervention on or in the eye, the ophthalmological intervention including cutting a flap in a cornea of the eye such that when the flap is folded upwards a region of a stroma is exposed for ablation, a computer controller for controlling the laser radiation in space and time in relation to the eye in order to cut the flap in accordance with a treatment program which is oriented towards a centre of the eye, a suction ring configured to be fixedly coupled to the eye and the focusing optics, a camera which records a pupil of the eye and at least a portion of the suction ring, and an image-processing unit in communication with the camera and the computer controller, wherein the image-processing unit derives information about the centre of the eye from a position of a center of the pupil from the recording of the camera and a local relationship between the position of the suction ring and the center of the pupil of the eye from the recording of the camera, the image-processing unit enters this information into the computer controller, wherein the computer controller controls the laser radiation in accordance with the treatment program to cut the flap in a manner depending on the centre of the eye and the local relationship between the position of the suction ring and the center of the pupil of the eye as derived by the image-processing unit such that a periphery of the flap is offset in relation to the center of the pupil.
