Clinical experience with the Tscherning aberrometer.
OBJECTIVE
With the aberrometer based on Tscherning's principle, measurements of wavefront aberrations of human eyes with high accuracy and reproducibility are available for standard diagnostic investigations.


METHODS
During investigational and clinical trials, wavefront-aberrations of about 300 human eyes were measured and evaluated within the last few years.


RESULTS
measurements are presented in terms of Zernike coefficients and as height maps that can be converted directly to ablation profiles for wavefront-guided laser treatments.


CONCLUSIONS
The Tscherning aberrometer is a simple optical device with high accuracy appropriate for routine clinical investigations on optical aberrations of the human eye.
