A Comparative Analysis Of Visual Quality After Implantation Of MF15 Intraocular Lenses And Symfony Intraocular Lenses

Objective:To compare the visual quality of cataract patients after implantation of zonal refractive(Lentis Comfort LS-313MF15)intraocular lenses and extended-range-of-vision(Tecnis Symfony)intraocular lenses(IOL),so It can provide reference for the selection of presbyopia-correcting intraocular lenses in clinic.Methods:A total of 305 eyes of 267 patients with cataract who underwent phacoemulsification combined with intraocular lens implantation in the Cataract Department of The Second Hospital of Ji Lin university were collected in this study,According to the different types of implanted intraocular lenses,they were divided into group A(Symfony,160 eyes)and group B(MF15,145 eyes).The Uncorrected Distance Visual Acuity(UDVA,5m),Uncorrected Intermediate Visual Acuity(UIVA,80 cm),Uncorrected Near Visual Acuity(UNVA,40cm),modulation transfer function(MTF),highorder aberrations(HOAs),including coma,spherical aberration and trefoil aberration,defocus curve and the Quality of Vision(Qo V)questionnaire were observed 3 months after surgery.Results:There were no significant differences in the preoperative examination results between the two groups(P>0.05).1.Visual Acuity:There was no significant difference between the UDVA and UNVA in Symfony and MF15(P>0.05);The UIVA was higher in Symfony than in MF15,and the difference was statistical significant(P<0.05);2.MTF:The MTF value in Symfony was higher than MF15 at all spatial frequency(5-30c/d),and the difference was statistical significant(P<0.05);3.HOAs:The HOAs(including coma,spherical aberration and trefoil aberration)in Symfony was lower than that in MF15(P<0.05);4.Defocus curves: The defocus curves of the two groups was relatively smooth from OD to-4.5D.From-0.5D to-2.5D,MF15 had worse visual acuity than Symfony;5.Qo V:The Qo V score in MF15 was significantly lower than that in Symfony(P<0.05).Compared with patients implanted with Symfony,patients implanted with MF15 had a lower proportion of "all the time" and "often" experience dysphotopsia(glare,halo and starburst)after cataract surgery.Conclusions:1.Both the MF15 IOL and Symfony IOL can provide the patients with stable UDVA and UNVA.2.Compared with patients implanted with MF15,patients implanted with Symfony had better UIVA,lower HOAs(including coma,spherical aberration and trefoil aberration)and higher contrast sensitivity.3.Compared with patients implanted with Symfony,patients imp lanted with MF15 had a lower proportion of "all the time" and "often" experience dysphotopsia(glare,halo and starburst)after cataract surgery.
