摘　　要：目的探讨短眼轴(眼轴<22.00mm)患者IOL计算公式屈光预测准确性。设计前瞻性病例系列。研究对象2021年12月至2023年5月西安市人民医院行白内障超声乳化吸出联合后房型单焦一片式IOL植入手术的短眼轴患者51例(56眼)。方法采用IOLMaster700测量眼轴、角膜曲率、中央前房深度、晶状体厚度,根据Holladay2、Haigis、Barrett UniversalⅡ公式预测术后屈光度数。最佳矫正视力转化成LogMAR视力进行统计分析。术后3个月进行显然验光,比较三种公式预测屈光度的误差。主要指标术后屈光预测误差和绝对预测误差。结果术前中央前房深度平均(2.2±0.2)mm,术后3个月平均(3.8±0.3)mm(t=25.7,P<0.001)。三种公式的预测误差和绝对预测误差之间均无统计学差异(P均>0.05)。公式Haigis预测误差76.9%分布在±0.50 D,优于公式Holladay2(50.0%分布于±0.50 D)和Barrett UniversalⅡ(57.6%分布在±0.50 D)。结论短眼轴患者基于IOLMaster700测量采用IOL公式Haigis、Holladay2、Barrett UniversalⅡ的准确性均较高。Objective To investigate the accuracy of intraocular lens(IOL)power prediction formulas in patients with short eyes(axial length<22.00 mm).Design Prospective case series study.Participants 51 patients(56 eyes)with short axial length who underwent phacoemulsification and posterior chamber single-piece monofocal IOL implantation surgery at Xi'an People's Hospital from December 2021 to May 2023.Methods The axial length,corneal curvature,central anterior chamber depth,and lens thickness were measured with IOLMaster700.Postoperative refractive error was predicted using Holladay2,Haigis,and Barrett Universal II formulas.The best corrected visual acuity was converted into LogMAR visual acuity for statistical analysis.Subjective optometry examination was performed at 3 months postoperatively.The errors in predicting refraction using the Haigis,Holladay 2,and Barrett Universal II formulas were compared.Main Outcome Measures Refractive prediction error and absolute prediction error.Results The average central anterior chamber depth preoperatively was(2.2±0.2)mm,which significantly increased to(3.8±0.3)mm at 3 months postoperatively(t=25.7,P<0.001).There were no statistically significant differences in prediction error and absolute prediction error among the three formulas(all P>0.05).The Haigis formula showed 76.9%of prediction errors distributed within±0.50 D,which was better than the Holladay 2 formula(50.0%within±0.50 D)and the Barrett Universal II formula(57.6%within±0.50 D).Conclusion The accuracy of IOL formulas(Haigis,Holladay 2,Barrett Universal II)based on IOLMaster700 is relatively high in patients with short axial length.
