Risk factors for refractive error after cataract surgery: Analysis of 282 811 cataract extractions reported to the European Registry of Quality Outcomes for cataract and refractive surgery

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.
