Abstract
The present solution is directed to the orientation of an eye for diagnostic and/or therapeutic purposes, wherein the line of sight need not coincide with the optical axis of the examination apparatus or treatment apparatus. The invention includes a fixating light source for generating a positionable fixating mark, a device for coupling this fixating mark into a beam path of an ophthalmological apparatus whose imaging optics project the fixating mark on the eye to be examined and/or treated, and a control unit by which the image of the fixating mark can be displayed at different distances and angular positions with respect to the optical axis of the ophthalmological apparatus so that the eye to be examined and/or treated is oriented to this fixating mark by foveal focusing and occupies a defined position with respect to the optical axis of the ophthalmological apparatus.
