Objective To evaluate the visual outcomes,depth of focus and safety after implantation of the Acrysof ReSTOR and the Acrysof Natural.Design Nonrandomized clinical trial.Participant 53 patients with age-related cataract(61 eyes)were divided into two groups:Acrysof ReSTOR group(MIOL)included 28 patients(31 eyes),and reference group-Acrysof Natural group(SIOL)included 25 patients(30 eyes).Method All patients underwent phacoemulsification and IOL implantation.At 1 week,1 month and 3 months postoperatively,distant and near visual acuities were observed,and depth of focus was measured 3 months postoperatively.Main Outcome Measure Uncorrected distant visual acuity(UCDVA),uncorrected near visual acuity(UCNVA),best corrected distant visual acuity(BCDVA),best corrected near visual acuity(BCNVA),distant corrected near visual acuity(DCNVA),depth of focus.Result At 3 months postoperatively,in MIOL group:UCDVA was 0.90?0.15,UCNVA was 0.70?0.19,DCNVA was 0.73?0.21 and depth of focus was 5.5D(+1.5～-4.0D),while in SIOL group:UCDVA was 0.84?0.14,UCNVA was 0.36?0.10,DCNVA was 0.26?0.08 and depth of focus was 2.5D(+1.0～-1.5D).In MIOL group,UCDVA and UCNVA at 1 month were markedly better than those at 1 week. Conclusion Acrysof ReSTOR can provide excellent outcomes both in distants and near visions and it may reduce the dependence on spectacles in near vision.(Ophthalmol CHN,2006,15:344-347)
