SD, standard deviation. The magnitude of astigmatism indicates the absolute value of cylinder power, regardless of the axis. Thibos and Horner’s method was used in the power vector analysis of astigmatism. values were calculated using the repeated-measure ANOVA, regarding the laterality of eye as a within-subject variable. < 0.05.
