Effect of phacoemulsification combined with implanting different aspheric intraocular lens on postoperative visual acuity and contrast sensitivity

Objective:To investigate the effects of phacoemulsification combined with implanting different aspheric intraocular lens on postoperative visual acuity and contrast sensitivity.Methods:Ninety-six cataract eyes(72 patients) were divided into group A,B and C.All cases were treated with phacoemulsification combined with implanting different aspheric intraocular lens.The AcrySof ReSTOR plus 3D(SN6AD1) aspheric multifocal intraocular lens,AcrySof ReSTOR plus 4D(SN6AD3) and monofocal intraocular lens were used in group A,B and C,respectively.The naked eye and corrected visual acuity,and contrast sensitivity in different lighting conditions and spatial frequency between 3 groups were compared at postoperative 1 day,1 week and 1 month.Results:The naked eye visual acuity in group A at postoperative 1 day,1 week and 1 month was significantly better than that in group B and group C(PP>0.05).The contrast sensitivities in group A and group B under non-glare(3 cd/m2) and 3 c/d and 6 c/d low spatial frequency were better than that in group C(P2) were better than that in group C(PConclusions:The phacoemulsification combined with implanting intraocular lens can significantly improve the visual quality of cataract patients.Compared with the monofocal intraocular lens,the effect of aspheric multifocal intraocular lens on improving the contrast sensitivity is better.The AcrySof ReSTOR plus 3D(SN6AD1) aspheric multifocal intraocular lens can significantly improve the distance vision of patients,which is worthy of clinical application.
