Abstract
An arrangement and method for positioning an ophthalmologic device with respect to the patient's eye to be examined in x-, y- and/or z-coordinates. The device includes a controllable illumination unit, an observation system, an image recording unit, a central control unit, an output unit, an eye tracker unit, and a device for relative positioning. The imaging system of the eye tracker unit has at least two different adjustable magnifications. In positioning the ophthalmologic device, the signal of the eye tracker unit is used to track a measuring mark and/or grid structure projected on the eye, and also to detect the position of the patient's eye with respect to the optical axis of the ophthalmologic device. The inventive solution makes it possible to automatically position the entire device with respect to the eye to be examined, thus simplifying examination and accelerating determination of biometric data.
