Correlations between prediction error and ablation zone decentration in post-myopic-LASIK eyes. In the lower K group (K value < 37.08 D), prediction error was negatively correlated with decentration with both formulas (a Haigis-L formula, Pearson’s r = − 0.353, P = 0.023; b Barrett True-K formula, Pearson’s r = − 0.369, P = 0.018). However, in the higher K group (K value ≥ 37.08 D), prediction error was not significantly correlated with decentration no matter which formula was used (all P > 0.05)
