研究概览
简要总结
This prospective observational study aims at assessing the refractive accuracy and visual outcomes inpatients that underwent cataract surgery with IOL implantation in which IOL power was obtained using Argos® biometer. The post-operative visual acuity and refractive error will be compared with the preoperative visual acuity and predicted post-operative refractive error on Argos® biometer. The main purpose of this study is to determine if Argos can accurately estimate the IOL power in long and short axial length eyes and provide consistent and accurate post-operative results
