To analyze risk factors for refractive error after cataract surgery and provide a benchmark for refractive outcomes after standard cataract surgery.
One hundred cataract surgery clinics from 12 European countries.
Multicenter database study.
Data on consecutive cataract extractions reported to the European Registry of Quality Outcomes for Cataract and Refractive Surgery between January 1, 2014 and December 31, 2015 were analyzed in terms of demographics, preoperative corrected distance visual acuity (CDVA), target refraction, coexisting eye diseases, surgical difficulties including previous ophthalmic interventions, type of surgery, intraocular lens (IOL), and surgical complications. For clinics committed to reporting follow-up data within 7 to 60 days after surgery, postoperative CDVA and refraction were analyzed.
Of the 548 392 cases analyzed, follow-up data were available for 282 811 cases. The absolute mean biometry prediction error in spherical equivalent was 0.42 diopters (D). A biometry prediction error within ±0.50 D was achieved for 205 675 eyes (72.7%). A biometry prediction error within ±1.0 D was achieved for 263 015 eyes (93.0%). Poor preoperative CDVA, target refraction, coexisting eye diseases, surgical difficulties including previous ophthalmic interventions, and surgical complications were in varying degrees related to a postoperative refractive error.
Several risk factors (poor preoperative CDVA, ocular comorbidity, and previous eye surgery) were related to poor refractive outcomes after cataract extraction. When these risk factors are present, care should be taken with the preoperative examination and choice of IOL to avoid a refractive surprise. The average outcomes can be used as a refractive outcome benchmark.
分析白内障手术后屈光不正的危险因素，并为标准白内障手术后的屈光结果提供基准。
来自 12 个欧洲国家的 100 家白内障手术诊所。
多中心数据库研究。
分析 2014 年 1 月 1 日至 2015 年 12 月 31 日期间向欧洲白内障和屈光手术质量结果登记处报告的连续白内障摘除数据，分析人口统计学、术前矫正远视力（CDVA）、目标屈光度、并存眼病、手术难度（包括先前的眼科干预）、手术类型、人工晶状体（IOL）和手术并发症。对于承诺在手术后 7 至 60 天内报告随访数据的诊所，分析术后 CDVA 和屈光度。
在分析的 548392 例病例中，有 282811 例获得了随访数据。球镜等效的绝对平均生物测量预测误差为 0.42 屈光度（D）。205675 只眼（72.7%）的生物测量预测误差在±0.50 D 以内。263015 只眼（93.0%）的生物测量预测误差在±1.0 D 以内。术前 CDVA、目标屈光度、并存眼病、手术难度（包括先前的眼科干预）和手术并发症较差，在不同程度上与术后屈光不正有关。
一些危险因素（术前 CDVA 差、眼伴发病和先前的眼部手术）与白内障摘除术后屈光结果不佳有关。当存在这些危险因素时，应注意术前检查和 IOL 的选择，以避免屈光意外。平均结果可作为屈光结果的基准。
