Results

The estimated IOL power was significantly lower at post-pIOL implantation according to the H and B formulae (both p < 0.001) but remained unchanged by the S formula. However, no difference was observed when AS-OCT-derived ACD and lens thickness (LT) values were introduced in the H (p = 0.16) and B (p = 0.55) formulae.
