Abstract: An opthalmological measuring instrument, e.g. for determining the corneal curvature, anterior chamber depth, axial length, or the like, including measuring systems for determining measurement of the mentioned physical parameters. The measuring systems are connected to an evaluation unit which verifies whether quality parameters regarding the measurements are satisfied and generates a corresponding signal that indicates to the medical professional user that a proper measurement can be taken.

Abstract: A spectrometer is described, especially for an optical coherence tomograph for detecting parameters of the human eye, with said spectrometer having an input for measurement radiation to be analyzed, fanning the measurement radiation spectrally out along a direction in a fan and guiding it onto a detector that extends along the direction and comprises a plurality of detector pixels that are sensitive to the measurement radiation, with the spectrometer having an adjusting element which can be adjusted in a controlled manner to adjust the relative position of the fan and the detector, thereby optimizing the incidence position of the fan on the detector, in which it is provided that the detector has at least two superimposed, adjacent pixel lines, and a control device is provided which reads out the superimposed pixels of a plurality of pixel lines in a combined manner for a spectral analysis of the measurement radiation in a pixel binning and evaluates signal differences between superimposed pixels to control th

Abstract: The invention relates to a method for determining distances in the anterior ocular segment, preferably of the pupils and/or the diameter of the iris, wherein the image of at least part of the eye is recorded and digitized using an imaging device and an array for illuminating the eye. On the basis of said digital image, a center of gravity analysis and the determination of the central point are carried out, especially for the position of the pupils, by conducting an intensity and threshold analysis as rough determination. Based on said rough determination, a fine detection of the position of the edges of the pupil and/or the edges of the iris is carried out. Additionally, the angle between the visual axis and the optical axis of the eye can be determined from the position of a fixed reflection to the center of the pupil and/or the center of the iris.
