Abstract

Background: To compare the accuracy of intraocular lens power calculation formulae after laser refractive surgery in myopic eyes.

Methods: We searched the databases on PubMed, EMBASE, Web of Science and the Cochrane library to select relevant studies published between Jan 1st, 2009 and Aug 11th, 2019. Primary outcomes were the percentages of refractive prediction error within ±0.5 D and ±1.0 D.

Results: The final meta-analysis included 16 studies using seven common methods (ASCRS average, Barrett True-K no history, Double-K SRK/T, Haigis-L, OCT formula, Shammas-PL, and Wang-Koch-Maloney). ASCRS average yielded significantly higher percentage of refractive prediction error within ±0.5 D than Haigis-L, Shammas-PL and Wang-Koch-Maloney (P = 0.009, 0.01, 0.008, respectively). Barrett True-K no history also yielded significantly higher percentage of refractive prediction error within ±0.5 D than Shammas-PL and Wang-Koch-Maloney (P = 0.01, P < 0.0001, respectively), and a similar result was found when comparing OCT formula with Haigis-L and Shammas-PL (P = 0.03, P = 0.01, respectively).

Conclusion: The ASCRS average or Barrett True-K no history should be used to calculate the intraocular lens power in eyes after myopic laser refractive surgery. The OCT formula if available, can also be a good alternative choice.

近视激光屈光手术后人工晶状体度数计算公式的准确性:一项荟萃分析。

背景:比较近视激光屈光手术后人工晶状体度数计算公式的准确性。方法:检索PubMed、EMBASE、Web of Science和Cochrane图书馆数据库，选取2009年1月1日至2019年8月11日发表的相关研究。主要结果是屈光预测误差在±0.5 D和±1.0 D范围内的百分比。结果:最终荟萃分析包括16项研究，采用7种常用方法(ASCRS平均、Barrett True-K无病史、Double-K SRK/T、Haigis-L、OCT公式、Shammas-PL和Wang-Koch-Maloney)。ASCRS平均在±0.5 D内的折光预测误差百分比显著高于Haigis-L、Shammas-PL和Wang-Koch-Maloney (P分别= 0.009、0.01和0.008)。Barrett True-K无病史的折光预测误差在±0.5 D内的百分比也显著高于Shammas-PL和Wang-Koch-Maloney (P = 0.01, P = 0.03, P = 0.01)。结论:应采用ASCRS平均值或Barrett True-K无病史来计算近视激光屈光手术后眼内晶状体度数。OCT公式如果可用，也是一个很好的替代选择。
