A system for the improved imaging of eye structures based on optical coherence tomography. The system includes an interferometric measuring arrangement, which has an optical element arranged in the measurement arm or reference arm for influencing the polarization state of the light before the light is interferometrically superimposed, a scanning unit arranged in the measurement arm for implementing OCT scans, a detector for recording the produced interference pattern, and an evaluating and documenting unit. At least two different polarization states of the light are produced. The interference patterns produced in the interferometric measuring arrangement are recorded and forwarded to the evaluating and documenting unit which reconstructs OCT scans from the transmitted interference patterns, combines the OCT scans, and presents and/or stores the resulting OCT signals. The system can be used for pachymetry in addition to the pre- and post-operative imaging for analysis and measurement.
