Correlations between prediction error and corneal ablation patterns in post-myopic-LASIK eyes. Prediction error was positively related to K value (a Haigis-L formula, Pearson’s r = 0.442, P < 0.001; b Barrett True-K formula, Pearson’s r = 0.235, P = 0.033) and negatively related to ablation zone area (c Pearson’s r = − 0.375, P < 0.001 for Haigis-L formula; d Pearson’s r = − 0.296, P = 0.007 for Barrett True-K formula) with both formulas. With the Barrett True-K formula, prediction error was negatively correlated with ablation zone decentration (e Pearson’s r = − 0.320, P = 0.003). D, diopter
