Table 1 Preoperative and postoperative refractive and visual parameters for the eyes implanted with spherical (sICL) and toric ICL (tICL) and corresponding inter-eye differences. The values represent the mean ± standard deviation (SD), data range; 95% confidence interval for the mean. p-value for inter-eye comparisons (statistical significance after Bonferroni adjustment p ≤ 0.002)
