Summary

A holographic optical coherence tomography (H-OCT) setup is used to detect the wavefront by means of phase reconstruction.

Detailed description

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.

Conditions

• Wavefront Aberration, Corneal
