PURPOSE
To evaluate whether depth of focus after the implantation of extended depth of focus (EDoF) intraocular lenses (IOLs) correlates with pupillary size.
METHODS
This retrospective case series study evaluated eyes undergoing cataract surgery with implantation of EDoF IOLs. At least one month postoperatively, the depth of focus (DoF) was measured to determine the correlation with pupillary size, age, anterior chamber depth (ACD), axial length (AXL), and corneal spherical aberrations (SA).
RESULTS
The study evaluated 64 eyes of 49 patients. The mean depth of focus was 2.67 diopters (D). The mean preoperative photopic pupil size was 3.36 mm. A significant negative association was found between preoperative photopic pupil size and depth of focus (r = 0.30, Pearson's correlation coefficient) and between preoperative mesopic pupil size and depth of focus (r = 0.274, Pearson's correlation coefficient).
目的
评估植入扩展景深（EDoF）人工晶状体（IOL）后景深与瞳孔大小的相关性。
方法
本回顾性病例系列研究评估了接受白内障手术并植入 EDoF IOL 的眼睛。术后至少一个月，测量景深（DoF）以确定与瞳孔大小、年龄、前房深度（ACD）、眼轴（AXL）和角膜球差（SA）的相关性。
结果
本研究共评估了 49 名患者的 64 只眼。平均景深为 2.67 屈光度（D）。术前明视瞳孔大小的平均值为 3.36 毫米。术前明视瞳孔大小与景深呈显著负相关（r=0.30，皮尔逊相关系数），术前中间光瞳孔大小与景深呈显著负相关（r=0.274，皮尔逊相关系数）。
