Method for producing OCT images and other images of an eye including reducing the intensity of reflected light

A method for measuring the geometric parameters of the eye. These measurements, known by the term biometrics, are particularly significant for the calculation of intraocular lenses after previous refractive cornea surgery. OCT images and other images are recorded simultaneously, the intensity of the reflected light generated during the OCT image recordings being lower by a factor of 2, by a factor of 10 or by a factor of 100, than the intensity of the illumination light of the other image recordings. The solution provides a method for producing other image recordings, in addition to OCT recordings, in the form of representations of the sclera or of the fundus, or keratometric, topographic or biometric measurements, or even short image sequences, for instance, while aligning the device with the eye.
