A method of continuously controlling fixation of a patient's eye during detection of biometric data of the patient's eye

摘要

The present invention relates to a method of obtaining biometric data of a patient's eye, in which fixation is monitored during the entire biometric. In the proposed method, information about fixation is extracted from at least one of the records and data already available or additionally acquired, depending on the different recording modes. According to the present invention, a central retinal OCT scan with absolute fixation information and a frontal image with relative fixation information with or without at least partial diffuse illumination are used for this purpose. Based on this extracted fixation information, subsequent evaluations use only biometric data obtained immediately before, at the same time, or immediately after the frontal image with accurate fixation. The method according to the invention is provided specifically for obtaining biometric data of a patient's eye, but is used in different measurement modes and applies to different measurement tasks where alignment of the object to be measured is important for the measurement result. You can also do it.
