摘　　要：目的:评估Haigis、SRK/T、Holladay 1和Holladay 2公式预测高度近视白内障患者拟植入人工晶状体屈光度的准确性。方法:前瞻性研究。选取2017-08/2021-11于我院就诊的眼轴长度(AL)≥26 mm的年龄相关性白内障患者168例168眼,根据术前IOL Master 700测得眼轴长度将纳入患者分为5组,其中A组患者37例37眼,26mm≤AL<27 mm;B组患者34例34眼,27 mm≤AL<28 mm;C组患者42例42眼,28 mm≤AL<29 mm;D组患者28例28眼,29 mm≤AL<30 mm;E组患者27例27眼,AL≥30 mm。术后3 mo进行主觉验光,计算各公式预测屈光度的平均算术误差(MNE)和平均绝对误差(MAE)。结果:各组中Haigis与Holladay 2公式的MNE与MAE相对较小,且随着眼轴的增长MNE与MAE并未明显增加,而SRK/T、Holladay 1公式随着眼轴的增长MAE与MNE则明显增大,其中C、D、E组中Holladay 1公式的MNE与MAE增大更为明显。结论:对于眼轴长度≥26 mm的年龄相关性白内障患者,采用Haigis和Holladay 2公式预测人工晶状体屈光度的准确性更高。AIM:To evaluate the accuracy of the formulas,including Haigis,SRK/T,Holladay 1,and Holladay 2,in predicting the diopter of the intraocular lens implanted in high myopia cataract patients.METHODS:Prospective study.A total of 168 cases(168 eyes)of age-related cataract with an axial length(AL)≥26 mm who were treated in our hospital from August 2017 to November 2021 were selected.According to the preoperative AL measured by IOL Master 700,the patients were divided into five groups,including 37 cases(37 eyes)in group A with 26 mm≤AL<27 mm,34 cases(34 eyes)in group B with 27 mm≤AL<28 mm,42 cases(42 eyes)in group C with 28 mm≤AL<29 mm,28 cases(28 eyes)in group D with 29 mm≤AL<30 mm,and 27 patients(27 eyes)in group E with AL≥30 mm.Subjective refraction was performed at 3 mo postoperatively,and the mean numerical error(MNE)and mean absolute error(MAE)of each formula for predicting diopters were calculated.RESULTS:The MNE and MAE of the Haigis and Holladay 2 formulas were relatively less in each group,and MNE and MAE did not significantly increase with the growth of the axial length.However,the MAE and MNE of the SRK/T and Holladay 1 formulas significantly increased with the growth of the axial length,with the MNE and MAE of the Holladay 1 formula increasing more significantly in groups C,D,and E.CONCLUSION:For patients with age-related cataract,with an axial length of≥26 mm,the accuracy of predicting the diopter of the intraocular lens using the Haigis and Holladay 2 formulas were higher.
