Abstract
A method is disclosed for determining a current position of an eye of a patient relative to an optical axis of a laser beam of a treatment apparatus. The method includes presetting a criterion characterizing the eye, determining a first target position of the eye relative to the optical axis, positioning a patient interface in a preset area in front of the optical axis, illuminating the eye during an approaching procedure of the patient interface to the eye, capturing a Purkinje image, which is associated with a cornea of the eye, by means of an optical capturing device during the approaching procedure, comparing the captured Purkinje image to the optical axis and determining the current position of the eye depending thereon, comparing the current position to the target position and with a deviation, outputting a control signal to a control device of the treatment apparatus.
