目的：本系统综述和荟萃分析旨在评估Yamane技术用于人工晶状体巩膜内固定（SF-IOL）的屈光结果，并比较常用的各种人工晶状体屈光力计算公式的预测能力。
方法：在Medline进行了文献检索，Scopus,和Cochrane图书馆数据库，用于2014年1月至2023年5月发表的文章。纳入符合预定纳入标准的研究并进行分析。评估的主要结果是屈光预测误差，定义为预测屈光度和术后明显屈光度之间的差异。
结果：11项研究符合纳入标准，累计样本量为615例患者（平均年龄：66.6岁）。使用了各种IOL配方，SRK/T是最常用的公式。所有公式组合的总平均屈光预测误差为-0.02D，无统计学意义(p=0.99)。单个公式的亚组分析也显示与任何公式的预测误差没有显著差异(p>0.05)。
结论：用于SF-IOL的Yamane技术显示出有希望的屈光结果，IOL功率计算公式的选择应根据患者特征和外科医生的偏好进行调整。没有一个公式比其他公式表现出更好的预测能力。需要进一步的研究来开发专门用于具有继发性无晶状体眼和较差的囊膜支撑的眼睛的配方。
OBJECTIVE: This systematic
review and meta-analysis aims to assess the refractive outcomes of the Yamane technique for intrascleral fixation of intraocular lenses (SF-IOL) and compare the predictive ability of the various intraocular lens power calculation formulae commonly used in conjunction with the technique.
METHODS: A literature search was conducted in the Medline, Scopus, and Cochrane Library databases for articles published from January 2014 to May 2023. Studies that met the predetermined inclusion criteria were included and subjected to analysis. The primary outcome evaluated was the refractive predictive error, defined as the difference between predicted refraction and post-operative manifest refraction.
RESULTS: Eleven studies met the inclusion criteria, with a cumulative sample size of 615 patients (mean age: 66.6 years). Various IOL formulae were used, with SRK/T being the most frequently adopted formula. The overall mean refractive predictive error for all formulae combined was -0.02 D, which was not statistically significant (p = 0.99). Subgroup analysis for individual formulae also showed no significant difference from predicted error for any formula (p > 0.05).
CONCLUSIONS: The Yamane technique for SF-IOL shows promising refractive outcomes, and the choice of IOL power calculation formula should be tailored based on patient characteristics and surgeon preference. No formula demonstrated superior predictive ability over others. Further research is needed to develop formulae specifically for eyes with secondary aphakia and poor capsular support.
