Slopes for horizontal (blue) and vertical (gray) changes in TCA with pupil displacements for subjects 20075 (left) and 20076 (right) under different optical corrections: defocus, defocus + astigmatism, and all aberrations. Slope estimates for changes in TCA with all aberrations corrected are reported for two measurement methods, subjective alignments and objective image-based. Error bars are standard errors of the slope estimates. Brackets show statistically significant comparisons (* p < 0.05, ** p < 0.01, *** p < 0.001).
