| Purpose:To compare the visual acuity,visual quality and satisfaction of patients after implantation of the zonal refractive(Lentis comfort LS-313 MF15)and diffractive(Tecnis ZMB00)multifocal intraocular lens(MIOL),and to evaluate the advantages and shortcomings of two MIOLs with different design principles to provide a reference for the clinical application of MIOLs.Methods:A total of 265 eyes of 265 patients with age-related cataract who underwent phacoemulsification combined with multifocal IOL implantation surgery at the Second Hospital of Jilin University from September 2020 to September 2021 were selected and divided into MF15 group(141 eyes of 141 cases,aged 49.0-79.0,mean aged 61.80 ± 9.83)and ZMB00 group(124 eyes of 124 cases,aged 45.0-76.0,mean aged 60.75 ± 7.3)according to the type of multifocal IOL implanted intraoperatively.The uncorrected distance visual acuity(UDVA,5 m),uncorrected intermediate visual acuity(UIVA,80 cm),uncorrected near visual acuity(UNVA,40 cm),the whole-eye modulation transfer function(MTF),the total higher-order aberration under 5 mm pupil diameter,including clover,spherical aberration and coma,defocus curves,the quality of vision(Qo V)questionnaire and satisfaction rating were observed 3 months after surgery.Results:1.There were no significant differences in the preoperative examination results between two groups(P>0.05).2.Both groups showed good UDVA(P>0.05);the UIVA of MF15 group was better than ZMB00 group,while the UNVA of ZMB00 group was better than MF15 group(P<0.001).3.The defocus curves showed that the visual acuity of two groups at 0D was similar.The defocus curve of MF15 group showed a trend of continuous visual range in the range of-0.5D to-1.5D and the visual acuity was better than ZMB00 group in this range.The defocus curve of ZMB00 group showed two peaks at 0D and-3.0D respectively,and the visual acuity in the range of-2.5D to-4.0D was better than that of MF15 group(P<0.05).4.MTF values at 3 months postoperatively were lower in MF15 group than in ZMB00 group patients at all spatial frequencies(P<0.001).5.The total higher-order aberration,spherical aberration,coma aberration,and cloverleaf aberration of the whole eye under 5 mm pupil diameter at 3 months postoperatively were higher in MF15 group than in ZMB00 group(P<0.001).6.The scores of Qo V questionnaire in MF15 group were lower than those in ZMB00 group at 3 months postoperatively(P<0.05),in which the composition ratios of glare frequency in MF15 group were: never 90%,occasionally 6%,frequently 4%,and always 0%,and those in ZMB00 group were: never 68%,occasionally 27%,frequently 10%,and always 5%(P<0.05);the composition ratio of the frequency of halos in MF15 group patients was: never 88%,occasionally 6%,frequently 3%,and always 3%,and the composition ratio of the frequency of halos in ZMB00 group patients was: never 46%,occasionally 26%,frequently 18%,and always 10%(P<0.05);the composition ratio of the frequency of auras in MF15 group patients was: never 91 %,occasional 6%,frequent 3%,and always 0%,and the composition ratio of the frequency of asterixis in ZMB00 group patients was: never 55%,occasional 23%,frequent 10%,and always 12%(P<0.05).There was no statistically significant difference in the satisfaction between the two groups at 3 months postoperatively(P>0.05).Conclusion:1.Both MF15 and ZMB00 IOLs offered excellent distance vision recovery and good optical quality.2.MF15 IOL provided more stable intermediate vision and less postoperative bad photic phenomena.3.ZMB00 IOL showed better near vision,contrast sensitivity,and objective optical quality.4.Both MF15 and ZMB00 IOLs received high level satisfaction in postoperative patients. |
