Paper Abstract

The optical quality for some special human eyes was evaluated from wavefront aberration data. Wavefront aberrations were measured by a ray-tracing wavefront aberrometer. The optical quality was estimated by means of objective and quantitative optical quality metrics of human eyes. The results show that the point spread function patterns and the values of six optical quality metrics vary with the individual eyes or the levels of aberration. The values of PFWc, SRX, AreaMTF and SRMTF increase, as well as the values of RMSs and SM decrease, with the more corrected aberration orders. The great increase of higher-order aberration may be attributed to the pathological changes or refractive surgery, which results in the distinct degeneration of optical quality of human eye.
