PURPOSE
To describe the different formulas that try to overcome the problem of calculating the intraocular lens (IOL) power in patients that underwent corneal refractive surgery (CRS).
METHODS
A Pubmed literature search review of all published articles, on keyword associated with IOL power calculation and corneal refractive surgery, as well as the reference lists of retrieved articles, was performed.
RESULTS
A total of 33 peer reviewed articles dealing with methods that try to overcome the problem of calculating the IOL power in patients that underwent CRS were found. According to the information needed to try to overcome this problem, the methods were divided in two main categories: 18 methods were based on the knowledge of the patient clinical history and 15 methods that do not require such knowledge. The first group was further divided into five subgroups based on the parameters needed to make such calculation.
CONCLUSION
In the light of our findings, to avoid postoperative nasty surprises, we suggest using only those methods that have shown good results in a large number of patients, possibly by averaging the results obtained with these methods.
目的
描述不同的公式，这些公式试图解决接受角膜屈光手术（CRS）患者的人工晶状体（IOL）屈光力计算问题。
方法
对所有已发表文章进行PubMed文献检索综述，检索关键词为与IOL屈光力计算和角膜屈光手术相关的内容，以及检索到文章的参考文献列表。
结果
共发现33篇经同行评审的文章，涉及试图解决接受CRS患者IOL屈光力计算问题的方法。根据试图解决该问题所需的信息，这些方法分为两大类：18种方法基于患者临床病史知识，15种方法不需要此类知识。第一组根据进行此类计算所需的参数进一步分为五个亚组。
结论
根据我们的研究结果，为避免术后出现不良意外情况，我们建议仅使用那些在大量患者中显示出良好效果的方法，可能通过对这些方法获得的结果进行平均。
