Average magnitude of Zernike coefficient with the conventional spherical and customized wavefront-guided optics SLPD in 11 eyes with advanced KC over a 6mm pupil. The Zernike coefficients are expressed according to the single value modes suggested in the ANSI Z80.28-2004 standard. The average higher order root-mean-square with the conventional and customized SLPD is also shown for the 11 KC eyes. The result of two-tailed, paired student’s t-test of statistical significance is indicated.
