摘　　要：目的:比较不同角膜曲率和前房深度短眼轴白内障人群7种人工晶状体计算公式的屈光预测准确性,并分析预测误差的影响因素。方法:回顾性分析了2020-11/2021-12在沈阳何氏眼科医院单纯行白内障超声乳化术的短眼轴患者125例125眼。按角膜曲率(Km)分为低平Km组(≤45.5 D)、中高Km组(45.5 D<Km<47 D)及陡峭Km组(≥47 D);按ACD分为极浅前房组(≤2.09 mm)、浅前房组(2.09 mm<ACD<2.58 mm)及正常深前房组(≥2.58 mm),计算EVO、 KANE、 Barrett UniversalⅡ、SRK/T、Hoffer Q、Holladay I及Haigis公式绝对预测误差中位数(MedAE),比较其屈光预测准确性及各种参数与预测误差的相关性。结果:总体比较时,各公式的预测误差存在显著差异(χ^(2)=49.934,P<0.001),Barrett UniversalⅡ公式的MedAE最小(0.17 D)。分组比较时,中高及陡峭Km组各公式的预测误差存在显著差异(χ^(2)=34.372、34.804,均P<0.001),Barrett UniversalⅡ公式的MedAE(0.14 D;0.20 D)最小;ACD 3个分组的各公式预测误差均存在差异(χ^(2)=22.863、25.568、13.647,均P<0.05),Barrett UniversalⅡ公式的MedAE(0.27 D;0.15 D;0.16 D)最小。多元线性回归分析显示Km、AL及IOL度数是导致术后预测误差的重要相关因素。结论:短眼轴人群在不同生物测量参数下Barrett UniversalⅡ公式较其他公式准确性更高,AL、Km及IOL度数与预测准确性密切相关。·AIM:To compare the refractive prediction accuracy of 7 intraocular lens(IOL) calculation formulas in the cataract eyes with short axial length(AL) at different corneal curvatures and anterior chamber depth(ACD),and analyze relevant influencing factors contributing to prediction errors.·METHODS:A retrospective analysis was performed for 125 patients(125 eyes) with a short AL,who received cataract phacoemulsification at Shenyang He Eye Specialist Hospital from November 2020 to December 2021.According to the keratometry(Km),they were divided into low flat Km group(≤45.5 D),medium and high Km group(45.5 D<Km<47 D) and steep Km group(≥47 D);and they were divided into extremely shallow anterior chamber group(≤2.09 mm),shallow anterior chamber group(2.09 mm<ACD<2.58 mm) and normal deep anterior chamber group(≥2.58 mm) according to the ACD.And then the median absolute error(MedAE) of EVO,KANE,Barrett Universal Ⅱ,SRK/T,Hoffer Q,Holladay I,and Haigis formulas was calculated and compared,and the correlation between various parameters and prediction error was analyzed.·RESULTS:There was a significant difference in the absolute prediction error of each formula(χ^(2)=49.934,P<0.001) in the overall comparative analysis,and the MedAE of the Barrett Universal Ⅱ formula was the smallest(0.17 D).There were significant statistical differences in the middle-high and steep Km groups(χ^(2)=34.372,34.804,all P<0.001),and the MedAE(0.14 D;0.20 D) of the Barrett Universal Ⅱ formula was the smallest.The absolute prediction error of the 3 ACD subgroups was statistically significant(χ^(2)=22.863,25.568,13.647,all P<0.05),and the MedAE(0.27 D;0.15 D;0.16 D) of the Barrett Universal Ⅱ formula was the smallest.Multiple linear regression analysis showed that Km,AL,and the IOL degree were important correlated factor leading to postoperative prediction error.·CONCLUSION:The accuracy of the Barrett Universal Ⅱ formula was higher in the short AL population under different biometric parameters,and AL,Km and IOL degree are cl
