Abstract
Objective To evaluate the effect of corneal curvature based on Sirius measurement on the accuracy of implantation of Acrysof Toric intraocular lens (IOL) and astigmatism correction.Methods In this prospective study,23 patients (36 eyes) with cataract and mild to moderate corneal astigmatism were recruited and underwent phacoemulsification and Acrysof Toric IOL implantation.In the observation group,the corneal curvature value of 19 eyes measured by Sirius was used as the basis for calculating Acrysof Toric intraocular lens power.In the control group,the corneal curvature value of 17 eyes measured by manual corneal curvature was used as the basis for calculating Acrysof Toric intraocular lens power.Main outcome measurements including uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA) surgically induced astigmatism(SIA),deviation of lens axis (LAD),index of corrected astigmatism (CAI) at 3 months postoperatively were observed.Results At 3 months postoperatively,the average UCVA of the observation group was (0.8 ± 0.11) and the average UCVA of the control group was (0.7 ± 0.73),there was no statistically significant differences (Z =1.277,P =0.372).The average BCVA of the observation group was (0.8 ± 0.21),and the average BCVA of the control group was (0.8 ± 0.41),there was no statistically significant differences (z =0.962,P =0.329).The deviation of lens axis of the observation group was (2.81 ± 1.72) ° and it was (3.12 ± 1.56)°in the control group,and there was no statistically significant differences (t =0.481,P =0.631).The index of corrected astigmatism of the observation group was (1.01 ± 0.21) and it was (1.03 ±0.32) in the control group,with no statistically significant differences (t =0.581,P =0.615).Conclusion Compared with the manual keratometer,Acrysof Toric IOL calculation based on Sirius measurement data is accurate and reliable.Meanwhile,Sirius has obvious advantages such as high resolution,non-contact,non-invasive and easy to operate.关键词
