Abstract：Objective To investigate the differences in visual acuity and visual quality after implantation of Tecnis Symfony IOL and Tecnis ZMB00 IOL in patients with age-related cataract.Methods From June 2022 to June 2023,a total of 63 patients(75 eyes)with age-related cataract who underwent phacoemulsification combined with IOL implantation in our hospital were enrolled in this study.Among these patients,39 cases(45 eyes)underwent the implantation of Tecnis Symfony IOL,while 24 cases(30 eyes)underwent the implantation of Tecnis ZMB00 IOL.The clinical indexes such as uncorrected distant visual acuity,intermediate visual acuity,near visual acuity(UCDVA,UCIVA,UCNVA)and defocus curve were observed at 3 months after operation.The quality of life and the rate of off-glass were evaluated by questionnaire analysis.Results At 3 months after operation,no statistical differences were observed in UCDVA(5 m)between two groups.The UCIVA of Symfony group was better than that of the ZMB00 group,and the UCNVA of ZMB00 group was better than that of Symfony group(P<0.001).At 3 months after operation,the defocus curve of Symfony group showed a continuous and stable trend in the range of+0 D～-2.0 D,with better UCIVA than ZMB00 group.The defocus curve in ZMB00 group showed a bimodal pattern,with peaks in the 0 D and-3.0 D,with better UCNVA than Symfony group.Questionnaire analysis showed that the rate of off-glass in the Symfony group and ZMB00 group was 92%and 96%,respectively.Conclusion Both Tecnis Symfony IOL and Tecnis ZMB00 IOL provide good visual quality for patients with age-related cataract.Tecnis Symfony IOL can provide extended range of vision,and Tecnis ZMB00 IOL can provide better UCNVA.
