摘要： A device for performing measurements on an eye (4), in particular for measuring the depth of the anterior chamber, the lens thickness, the corneal thickness or the axial length, wherein the device comprises an interferometer (10), focuses at least one measurement beam (7, 8) into the eye (4) along an optical axis (OA), records backscattered radiation and interferometrically generates a measurement signal displaying structures of the eye by time-domain, spectral-domain or Fourier-domain coherence reflectometry, has an adjustment apparatus (13; 16; 17; 19; 21) for laterally and/or axially displacing the focus in the eye (4) or for varying a polarization state of the measurement beam (7, 8) and has a control apparatus (22) which actuates the interferometer, wherein the control apparatus (22) generates a plurality of A-scan individual signals from the backscattered radiation, combines these to an A-scan measurement signal and is designed such that it actuates the adjustment apparatus (13; 16; 17; 19; 21) for displacing the position of the focus or for varying the polarization while recording the backscattered radiation from which the control apparatus (22) generates the A-scan individual signals is being recorded and backscattered radiation contributes to the A-scan measurement signal in a plurality of different positions of the focus or in a plurality of different polarization states of the measurement radiation (7, 8).
