Comparison Of Visual Acuity And Quality After Regional Refraction Multi-focus Intraocular Lens Implantation And Single-focus Intraocular Lens Implantation

Objective:To compare and analyze the visual quality of the refracting multifocal intraocular lens LS-313 MF15 and the monofocal intraocular lens Tecnis ZCB00 after implantation.Methods:The subjects of this study were 277 patients(277 eyes)who underwent cataract ultrasound emulsification combined with IOL implantation from March 2020 to October 2021 in this medical group,divided into ZCB00 groups(n=146)and MF15(n=131)from March 2021 to October a type of intrauterine lens.The ZCB00 group implanted the mono-focal intrauterine lens(AMO,USA,ZCB00),and the MF15 group implanted a refractive multifunctional intrauterine lens(Oculentis,Netherlands,LS-313 MF15).Patients were scanned three months after surgery and were observed and compared with two groups of high order aberrations(tHOs,SA,coma,and trefoil),modulation transfer function,questionnaire research,and lens loss rates in the distance,as well as the best adjusted long-distance vision,deconcentrated curve and space,high-order aberration(total high-order aberration(tHOs),spherical aberration(SA),coma,Trefoil),modulation transfer function value(MTF),questionnaire research,and adverse optical interference between two groups three months after surgery.Results:1.Visual acuity:There was no significant difference of distant vision in the two groups 3 months after surgery(P>0.05),and MF15 group had better UIVA and UNVA than ZCB00 group(P<0.05).2.Defocus curve and area under curve:The two groups of defocusing curves showed that the curve of MF15 group fluctuated slowly in the range of+0.5D--2.0D,and the ZCB00 group had a peak in 0D and then decreased;There was no significant difference in the DAUC between the two groups,and TAUC,IAUC and NAUC were significantly different in the MF15 group than in the ZCB00 group(P<0.05).3.High-order aberrations:tHOs,SA,coma,and trefoil in the MF15 group were higher than those in the ZCB00 group,and the differences were statistically significant(P<0.05).4.MTF value:The MTF value and the value of each spatial frequency of group ZCB00 was higher than that of group MF15,and the difference was statistically significant(P<0.05).5.Questionnaire and spectacle independence:VF-14 scale showed that the score of MF15 group was better than that of ZCB00 group(P<0.05),the QoV questionnaire showed that the score of ZCB00 group was less than that of MF15 group(P<0.05),the proportion of glare and starbust patients in the MF15 group was heavier than that in the ZCB00 group(P<0.05),while there was no significant difference about the halo between the two groups(P>0.05).The MF15 group has higher spectacle independence than that in the ZCB00 group at 3 months after surgery(P<0.05).Conclusion:1.Both groups had good naked eye distant vision and corrected distant vision;The refractive IOL in MF15 region has better medium and near vision than ZCB00 single focus IOL,and the defocus curve is smoother and the area under the curve is larger.2.Compared with the refraction IOL in MF15 region,ZCB00 singlefocus IOL has higher MTF value and lower high-order aberration.3.The subjective visual quality of ZCB00 single-focus IOL is better than that of the refraction IOL in MF15,which has a higher demirrorization rate.4.The patient should be fully communicated with before the operation,and the personalized IOL should be selected according to the different needs of the patient and in strict accordance with the Expert Consensus on the Clinical Application of Multifocal Intraocular Lens in China.
