目的系统比较不同人工晶状体(IOL)屈光度计算公式在浅前房白内障患者中的准确性。
方法计算机检索外文数据库MEDLINE、EMBASE、Cochrane Library以及中文数据库中国知网、万方数据、维普数据库自建库起至2020年8月发表的关于IOL屈光度计算公式在浅前房白内障患者中的准确性同行评议文献,根据纳入标准和排除标准进行文献筛选、资料提取和质量评价,选择不同公式间平均绝对误差(MAE)的平均差( MD)作为观察指标,采用RevMan 5.3软件进行meta分析。
结果本研究共纳入7篇文献,总计499眼。对6种IOL屈光度计算公式(Barrett Universal Ⅱ、Haigis、SRK/T、Hoffer Q、Holladay 1和Holladay 2)进行比较结果显示,Barrett Universal Ⅱ公式的MAE低于Hoffer Q公式( MD:0.11 D;95% CI:0.05~0.17 D; P<0.001)、Haigis公式( MD:0.08 D;95% CI:0.03~0.13 D; P=0.002)和Holladay 2公式( MD:-0.06 D;95% CI:-0.11~-0.01 D; P=0.020),差异均有统计学意义。其余公式之间的配对比较,差异均无统计学意义(均 P>0.05)。
结论Barrett Universal Ⅱ公式在预测浅前房白内障患者IOL屈光度方面优于Hoffer Q公式、Haigis公式和Holladay 2公式。
ObjectiveTo systematically compare the accuracy of intraocular lens (IOL) power calculation formulas in cataract patients with shallow anterior chamber.
MethodsA comprehensive literature search was conducted in MEDLINE, EMBASE, Cochrane Library, and the Chinese databases including CNKI, Wanfang, and VIP databases.The peer-reviewed literature on the accuracy of IOL power calculation formulas in cataract patients with shallow anterior chamber was searched from the establishment of the database until August 2020.Literature screening, data extraction and quality assessment were performed according to inclusion and exclusion criteria.The mean difference ( MD) of mean absolute error (MAE) among different formulas was analyzed.Meta-analysis was performed using Revman 5.3 software.
ResultsSeven studies involving 499 eyes were included.The accuracy of six formulas, Barrett Universal Ⅱ, Haigis, SRK/T, Hoffer Q, Holladay 1 and Holladay 2, was evaluated.The MAE of Barrett Universal Ⅱ was significantly lower than that of Hoffer Q ( MD=0.11 D; 95% CI: 0.05-0.17 D; P<0.001), Haigis ( MD=0.08 D; 95% CI: 0.03-0.13 D; P=0.002), and Holladay 2 ( MD=-0.06 D; 95% CI: -0.11--0.01 D; P=0.020). No significant difference was found in the remaining pairwise comparisons (all at P>0.05).
ConclusionsThe Barrett Universal Ⅱ formula is more accurate than Hoffer Q, Haigis, and Holladay 2 formulas in predicting IOL power in cataract patients with shallow anterior chamber.
