Table 2 Preoperative and postoperative anatomical and ICL-related parameters of the eyes implanted with spherical (sICL) and toric ICL (tICL); and corresponding inter-eye differences. The values are represented by the mean ± standard deviation (SD), data range and the 95% CI for the mean. p-value for inter-eye comparisons (statistical significance after Bonferroni adjustment p ≤ 0.002)
