目的：评价Haigis-L公式与临床资料法SRK/T公式（ CH-SRK/T）预测近视患者准分子激光原位角膜磨镶术（ laser in situ keratomileusis ，LASIK）术后人工晶状体度数的差异。方法：选取我院2012-10/2013-02手术患者72例140眼，眼轴≤26mm，排除其他眼部疾病。分别用Haigis-L，CH-SRK/T计算LASIK手术后人工晶状体度数，用SPSS 18．0统计软件进行统计学分析。结果：Haigis-L公式计算LASIK术后豪雅人工晶状体度数平均值为22．99±1．38D， CH-SRK/T计算豪雅人工晶状体度数平均值为19．95±1．69 D，配对样本均数t检验，成对差分均值-3．039±1．899D，Wilcoxon 带符号秩检验，秩和为-3．408a，P＝0．001；Haigis-L公式所测得LASIK术后眼力健AR40人工晶状体度数为23．26±1．49D，CH-SRK/T公式所测得LASIK术后眼力健AR40人工晶状体度数的平均值为20．05±1．69D，配对样本均数t检验，成对差分均值为-3．208±1．823 D，Wilcoxon带符号秩检验，秩和为-3．408 a ，P＝0．001。结论：近视患者LASIK术后人工晶状体度数用CH-SRK/T较Haigis-L公式测定结果低，照此植入人工晶状体术后更容易偏向欠矫。

AIM: To evaluate the differences between Haigis-L formula and CH-SRK/T when predicting intraocular lens power after laser in situ keratomileusis ( LASIK) surgery for myopia. METHODS: Seventy-two patients ( 140 eyes, axial length ≤ 26mm ) after LASIK surgery were recruited between October 2012 and February 2013. Participants with other ophthalmic diseases were excluded.Haigis-L and CH -SRK/T formula were used to calculate the intraocular lens power separately after LASIK surgery and the data were analyzed using SPSS 18.0 software. RESULTS:The mean value of Hoyaintraocular lens after LASIK was 22.99 ±1.38D by Haigis-L formula compared with 19.95±1.69D using CH-SRK/T formula.According to paired t-test, pairs of differential mean are -3.039 ± 1.899D.Wilcoxon signed rank test was used and the sum of ranks was -3.408a(P=0.001).Meanwhile, the mean value of Allergan AR40 intraocular lens was 23.26 ±1.49D by Haigis-L formula; while the degree of intraocular lens calculated by CH-SRK/T formula was 20.05 ±1.69D. According to paired t-test, pairs of differential mean are -3.208 ±1.823D.Wilcoxon signed rank test was used and the sum of ranks was -3.408a(P=0.001). CONCLUSION: After LASIK surgery for myopia, the degree of intraocular lens power measured by CH-SRK/T is lower than that by Haigis-L formula.The degree of intraocular lens power calculated by CH-SRK/T is more likely to be under corrected.
