摘要
目的探讨分析白内障超声乳化术后低视力(术后最佳矫正视力<0.3)的原因。方法对行白内障超声乳化摘除并人工晶状体植入术的960例(1240眼)患者的临床资料进行分析,观察术中术后并发症情况、术后低视力情况,分析术后低视力的原因。结果 960例(1240眼)中术中发生晶状体后囊膜破裂3眼,未有晶状体核坠入玻璃体腔。术后主要为角膜水肿,经常规治疗后所有患者水肿在术后1个月内消失。术后1240眼中最佳矫正视力<0.3者146眼,其中年龄相关性黄斑变性52眼,糖尿病性视网膜病变48眼,高度近视视网膜病变36眼,角膜斑翳4眼,视神经萎缩6眼。结论白内障术前需详细检查,充分评估患者可能并发的其他病变,对术后视力正确认识,降低患者术后预期,更好地规避手术风险。
Objective To investigate and analyze the cause of low vision（best corrected visual acuity after surgery 0.3） after phacoemulsification of cataract. Methods The clinical data of 960 patients（1240 eyes） with phacoemulsification and intraocular lens implantation were analyzed. The postoperative complications and postoperative low vision condition were observed, and the causes of postoperative low vision were analyzed. Results There were 3 eyes with intraoperative posterior capsular rupture in 960 cases（1240 eyes）, and no lens nucleus falling into vitreous cavity. Corneal edema occurred mainly after operation, and it disappeared within 1 months after regular treatment. There were 146 eyes with best corrected visual acuity 0.3 after operation in 1240 eyes, including 42 eyes with age-related macular degeneration, 48 eyes with diabetic retinopathy, 36 eyes with high myopia retinopathy, 4 eyes with corneal opacities and 6 eyes with atopic atrophy. Conclusion Before cataract surgery, detailed examination should be carried out to fully assess the possible complications. Let the patients correctly understand the postoperative visual acuity, reduce the postoperative expectations, so as to better avoid the operation risk.
