There are an increasing number of people who have had refractive surgery now developing cataract. To compare the accuracy of different intraocular lens (IOL) power calculation formulas after laser refractive surgery (photorefractive keratectomy or laser in situ keratomileusis), a comprehensive literature search of PubMed and EMBASE was conducted to identify comparative cohort studies and case series comparing different formulas: Haigis-L, Shammas-PL, SRK/T, Holladay 1 and Hoffer Q. Seven cohort studies and three observational studies including 260 eyes were identified. There were significant differences when Hoffer Q formula compared with SRK/T, Holladay 1. Holladay 1 formula produced less prediction error than SRK/T formula in double-K method. Hoffer Q formula performed best among SRK/T and Holladay 1 formulas in total and single-K method. In eyes with previous data, it is recommended to choose double-K formula except SRK/T formula. In eyes with no previous data, Haigis-L formula is recommended if available, if the fourth formula is unavailable, single-k Hoffer Q is a good choice.
现在越来越多接受过屈光手术的人出现了白内障。为了比较激光屈光手术后（准分子激光角膜切削术或飞秒激光原位角膜磨镶术）不同人工晶状体（IOL）计算公式的准确性，对 PubMed 和 EMBASE 进行了全面的文献检索，以确定比较队列研究和病例系列研究，比较不同公式：Haigis-L、Shammas-PL、SRK/T、Holladay 1 和 Hoffer Q。确定了 7 项队列研究和 3 项观察性研究，共 260 只眼。Hoffer Q 公式与 SRK/T、Holladay 1 公式相比有显著差异。Holladay 1 公式在双 K 法中比 SRK/T 公式产生的预测误差更小。在 SRK/T 和 Holladay 1 公式中，Hoffer Q 公式在总眼和单 K 法中表现最好。在有既往数据的眼中，建议选择双 K 公式，除非使用 SRK/T 公式。在没有既往数据的眼中，如果有 Haigis-L 公式可用，则建议使用，如果第四种公式不可用，则单 K Hoffer Q 是一个不错的选择。
