Abstract

See full text

A method for capturing biometric measurement data of a patient's eye, in which the fixation is monitored during the entire biometric measurement. Information in respect of the fixation is extracted, depending on the different recording modes, from already available or additionally captured recordings and/or data. Central retinal OCT scans with absolute fixation information and frontal images with relative fixation information with or without at least partial diffuse lighting are used. On the basis of this extracted fixation information, the subsequent evaluation only uses the captured biometric measurement data captured just before, at the same time as or just after frontal images with the correct fixation. The method can also be applied to different measurement tasks, in which use is made of different measurement modes and in which the alignment of the measurement object is important for the measurement results.
