The predicted IOL power was presneted as mean (SD). Bold values indicated significant differences based on p value.
*Indicated p < 0.05 for IOL power different from that predicted at baseline (T0).
aRepeated measures ANOVA showed there was significant differences among the IOL power predicted in PAC/PACG group using SRK/T, but Bonferroni-adjusted pairwise post hoc comparison did not reveal any significant difference between any two of the three time points.
