H-OCT will be tested in this study for its suitability for the qualitative investigation of aberrometry. We aim to achieve a digital equivalent for wavefront calculation of the widespread analog procedure commonly used with conventional wavefront-aberrometers. The results will be compared with those from a conventional analog wavefront calculation method.~In the course of this pilot study, 20 eyes of phakic and 10 eyes of pseudophakic subjects with suspected higher order aberrations will be examined using H-OCT.
A holographic optical coherence tomography (H-OCT) setup is used to detect the wavefront by means of phase reconstruction.
