摘　　要：目的:分析小切口白内障摘除人工晶状体植入术后低视力的相关因素。方法:回顾性分析我院2011-07/2012-07间白内障患者291例291眼,对其行小切口白内障囊外摘除联合人工晶状体植入术,最佳矫正视力低于0.3者诊断为低视力,并分析其发生原因。结果:患者291例术后共发生低视力49眼,其中手术所致术后低视力17眼(34.7%),术前病变所致术后低视力32眼(65.3%),其中年龄相关性黄斑变性8眼、糖尿病视网膜病变14眼、高度近视6眼,其他4眼。结论:原有眼病是术后低视力的主要原因,术前仔细检查可以提高手术的可预测性。AIM： To investigate the causative factors of low vision after small incision cataract surgery. METHODS： A retrospective study was made of 291 cataract patients （291 eyes） who received small incision cataract surgery combined with intraocular lens implantation from July 2011 to July 2012. Best corrected vision lower than 0.3 was diagnosed as low vision, and its causes were analyzed. ~ RESULTS： After surgery, low vision was diagnosed in 49 eyes. Of these cases, 17 （34.7%） were due to surgical complications and 32 （65.3%） were due to preoperative conditions, including age-related macular degeneration （8 eyes）, diabetic retinopathy （14 eyes）, high myopia （6 eyes） and other diseases （4 eyes）. CONCLUSION： In our study, presence of diseased conditions before surgery is the most important cause of low vision after small incision cataract surgery. Close examination before surgery can improve the predictabilit＇ of the surgery.
