摘　　要：Purpose:To evaluate the influence of corneal ablation patterns on the prediction error after cataract surgery in postmyopic-LASIK eyes.Methods:Eighty-three post-myopic-LASIK eyes of 83 patients that underwent uneventful cataract surgery were retrospectively included.Predicted postoperative spherical equivalence(SE)was calculated for the implanted lens using the Haigis-L and Barrett True-K formula.Prediction error at one month postsurgery was calculated as actual SE minus predicted SE.For each eye,area and decentration of the ablation zone was measured using the tangential curvature map.The associations between prediction errors and corneal ablation patterns were investigated.Results:The mean prediction error was-0.83±1.00 D with the Haigis-L formula and-1.00±0.99 D with the Barrett True-K formula.Prediction error was positively correlated with keratometry(K)value and negatively correlated with ablation zone area using either formula,and negatively correlated with decentration of the ablation zone using the Barrett True-K formula(all P<0.05).In the K<37.08 D group,prediction error was negatively correlated with decentration of the ablation zone with both formulas(all P<0.05).Multivariate analysis showed that with the Haigis-L formula,prediction error was associated with axial length(AL),K value and decentration,and with the Barrett True-K formula,prediction error was associated with AL and decentration(all P<0.05).Conclusion:A flatter cornea,larger corneal ablation zone and greater decentration will lead to more myopic prediction error after cataract surgery in post-myopic-LASIK eyes.
