Abstract
Objective To investigate the residual astigmatism and surgically induced astigmatism (SIA) after implantation of Acrysof Toric intraocular lens (IOL).Methods Totally 52 patients (62 eyes) who underwent phacoemuisification with Acrysof Toric IOL implantation from February 2016 to June 2017 were retrospectively reviewed.Observation of the variables including the uncorrected visual acuity,best corrected visual acuity,refraction,corneal curvature was performed,and individual SIA,mean SIA plus centroid SIA were calculated before surgery and one month after surgery.Results There was significant difference between postoperative anticipated astigmatism and postoperative actual astigmatism [(0.17 ± 0.15) D vs.(0.492 ± 0.37) D] (P ＜ 0.05).Preoperative corneal astigmatism was (1.94 ± 0.75) D,ranging from 0.93 D to 3.70 D,and postoperative corneal astigmatism was (1.95 ± 0.80) D,ranging from 0.68 D to 3.80 D.The individual SIA was 0.08-1.39 (0.44 ± 0.25) D,the mean SIA of 0.44 D,and centroid SIA of 0.12 D@126°.Conclusion It is precise and stable for Barrett Toric formula and centroid SIA to calculate the degree of Toric IOL,but there is still residual astigmatism after IOL implantation,so further optimization of SIA is still needed.关键词
