目的：探讨白内障超声乳化联合人工晶状体植入术后视力增进对老年人躯体及认知功能的影响。 方法：筛查年龄相关性白内障患者64例，其中40例行白内障超声乳化联合人工晶状体植入术,因故未经手术干预者设为对照，采用功能独立性评定量表（functional independence measure, FIM）、老年人活动与跌倒效能量表（survey of activities and fear of falling, SAFE）、简易精神状态检查表（mini mental state exam, MMSE）等评定术前及随访6mo的躯体及认知功能。 结果：经干预后视力均显著增进，FIM，SAFE评分提高，和基线值及对照组比较，差异有显著意义；MMSE评分降低,与对照组差异有显著性意义。 结论：视力增进可改善老年人躯体功能，对认知功能无积极效应。

AIM:To evaluate the effect of vision improvement induced by phacoemulsification on physical and cognitive function in aged adults. METHODS:A total of 64 cases with age-related cataract were enrolled in this study.Phacoemulsification combined with intraocular lens implantation was performed on 40 cases and the others who were eligible for but declined cataract surgery were allocated to a control group. Physical function was assessed using functional independence measure (FIM), survey of activities and fear of falling (SAFE) measure at baseline and 6 months after surgery. The mini mental state exam (MMSE) was also administered for cognitive function assessment. RESULTS:Significant difference existed within or between groups from baseline to follow-up on either of the measures of physical function. MMSE scores declined in both groups postoperatively.Significant difference was observed in the control group but not in the cataract surgery group. CONCLUSION:Vision enhancement induced by phacoemulsification leads to improvement in physical function but not in cognitive function.
