Clinical Study Of ReSTOR Multifocal Intraocular Lenses With A +3 Diopter Addition Power

Objective:1,To evaluate functional outcomes after bilateral implantation of ReSTOR Aspheric multifocal introcular lenses with a+3 or +4 diopter addition power.2,Evaluation of visual performance and satisfaction after simple implantation of ReSTOR Aspheric multifocal introcular lenses with a+3 diopter addition power.3,Visual function of special cataract after implantation of ReSTOR Aspheric multifocal introcular lenses with a+3 diopter addition power.Methods:1,50 patients with bilateral cataract were collected and observed by prosbective nonrandom method. Of the 50 patients,25 were in the +3D group which were implantded bilaterally with AcrySof IQ ReSTOR with a+3D add power, and 25 were in the +4D group which were implantded bilaterally with AcrySof IQ ReSTOR with a+4D add power. The follow-up period was 6 months. Overall visual acuity, contrast sensitivity, defocus testing, patient-reported outcomes were assessed.2,Bilateral cataract with simple cornea astigmatic were collected.15 in test group,non-astigmatic were impanted ReSTOR+3D, another were impanted AcrySof Toric.12 in control group, non-astigmatic were impanted AcrySof IQ, another were impanted AcrySof Toric. Overall visual acuity of simple and bilateral, contrast sensitivity, stereoscopic acuity, patient-reported outcomes were assessed.3,16 high myopia patients with bilateral cataract were collected after implanted with ReSTOR +3D. The follow-up period was 6 months.General state, visual acuity, refraction state, patient-reported outcomes were assessed.30 senility patients with bilateral cataract were divided into tow groups.15 were implanted with ReSTOR +3D,15 were implanted with AcrySof IQ. The follow-up period was 6 months. Visual acuity, defocus testing, patient-reported outcomes were assessed.Results:1,Binocular intermediate visual acuity was statistically significantly better in the+3.0 D group than that in the+4.0 D group (P<0.05); there was no difference in binocular near or distance visual acuity. There were no statistically significant differences in contrast sensitivity and visual disturbances between the 2 groups. Patients in both groups reported excellent overall spectacle independence, and satisfaction with the IOLs.2,There was no statistically significant difference between ReSTOR and Toric at intermediate and distant vision. ReSTOR eyes showed better near vision(P=0.000). But Toric eyes gain excel contrast sensitivity in high frequency and night light.The trail group gain better bilateral near vision, larger focal depth range, and near Stereoscopic acuity without notability abnormity. All patients represent without clear visual disturbance.3,There was statistically significant difference of vision change after high myopia with cataract were implanted with ReSTOR+3D MIOL (P=0.036), distant spectacle independence was 68%, near spectacle independence was approximately 100%. 1m refraction state was-0.81±0.68.Conclusion:1,Intermediate vision is better of the aspheric IOL with a+3.0 D add than of the aspheric IOL with a+4.0 D add; near and distance acuity are similar between the 2 IOLs. Patients report excellent overall quality of vision, spectacle independence, and satisfaction.2,ReSTOR +3D MIOL can offer better near vision with lower contrast sensitivity in high frequency and night light. One eye with ReSTOR another with Toric can obtain higher spectacle independence, and without clear visual disturbance.3,The group of ReSTOR +3D MIOL should propriety enlage, high myopia and senility can all obtain better overall vision with ReSTOR +3D. Preoperative we need carried out an assessment of patient's condition.
