摘　　要：目的分析超声乳化人工晶状体植入术后低视力因素。方法对829例856眼白内障超声乳化人工晶状体植入术后低视力因素进行回顾性研究,并以手术后3个月视力结果为标准,将手术后视力恢复低于0.5的患眼作为低视力眼进行统计学分析。结果856眼术后3个月低视力87眼,主要分布于非老年性白内障患眼(74/87,85.1%,χ2=641.29,P=0.0000);白内障手术后引起低视力的主要因素包括:术前因屈光间质不清,存在难以判断的视网膜视神经等疾病(64/87,73.6%),术中术后发生如角膜失代偿、后囊破裂、后囊混浊、黄斑囊样水肿等并发症(23/87,26.4%)。结论在白内障超声乳化人工晶状体植入手术前应加强对白内障患眼特别是非老年性白内障患眼的视功能评估,对眼底疾病采取联合治疗方法,以减少术中术后并发症。OBJECTIVE To analyze the related factors infecting the final visual results after cataract surgery. METHOD The factors caused low vision were studied retrospectively after Phacoemulsification with IOL surgery in 856 cataract eyes. The final visual results of three months after surgery in operated cataract eyes were taken as criterion,the visual acuity recovery that was not more than 0.3 was analyzed with statistics way. RESULTS Results There were 87 low vision eyes in 856 operated cataract eyes and they were distributed manly in the group of non senile cataract eyes（74/87,85.1%, χ^2 = 641.29, P = 0.0000）,the chief factors caused low vision after cataract surgery included the disease of retina and optic nerve that were not diagnosed before operation because of lens and vitreous opacity（64/87, 73.6 % ）, the complications of corneal edema, posterior capsule rupture（ PCR） and opacity, cystoids macular edema（CME） happened during or after the surgery（23/87,26.4 %）.CONCLUSIONS In order to gain successful visual acuity recovery after the PHACO surgery, it is necessary to do detailed assessment in all cataract eyes especially in non senile cataract eyes, to do proper treatment of fundus disease and to reduce the complication during and after the operation.
