Abstract:
Objective To compare the sensitivity of regional refraction multifocal intraocular lens implantation with other methods. Methods A total of 78 patients with simple cataract treated by visual acuity in our hospital from February 2016 to June 2017 were selected as subjects.The patients were divided into SBL-3 group (26 cases),SN6AD1 group (26 cases) and ZMB00 group (26 cases) according to the different intraocular lens.The contrast sensitivity value of patients in 3 groups under clear light(85 cd/m2),dark light(3 cd/m2),clear and glare light(45 Lux),dark and glare light(28 Lux) with different spatial frequencies (3,6,12,18 c/d) by the United States CSV-1000E contrast sensitivity tester after surgery.Results In terms of sensitivity index as clear light,dark light,clear and glare light,and dark and glare,the SBL-3 group were better than those of ZMB00 group and SN6AD1 group,the difference was significant(P<0.05);there were no significant differences between ZMB00 group and SN6AD1 group of each index sensitivity(P>0.05).Conclusion The postoperative sensi-tivity of refractive multifocal intraocular lens implantation of SBL-3 is significantly better than the apodized diffractive multifocal intraocular lens implantation of SN6AD1 and alll optical diffractive multifocal intraocular lens implantation of ZMB00,which is worthy of widely use for simple cataract.
