Abstract

目的 探讨晶状体超声乳化术中改良亚甲蓝染色和台盼蓝染色对连续环形撕囊成功牢及对角膜内皮的影响.方法 67例(67眼)白色白内障(术中无红光反射者)随机分为3组进行前瞻性研究.改良亚甲蓝染色组25例,台盼蓝染色组24例,对照组(前囊不染色)18例.连续环形撕囊后行超声乳化及人工晶状体植入术.比较环形撕囊成功率、术中并发症、术后前房反应情况、视力、眼压、角膜内皮损失率及变异系数.结果 两种方法染色后撕囊成功率及人工晶状体囊袋内植入牢均为100.00%,无后囊破裂,与对照组相比差异有统计学意义;染色组术后视力高于对照组,但差异无统计学意义;3组术后眼压及角膜内皮损失率和变异系数筹异均无统计学意义.结论 改良亚甲监染色和台盼蓝染色均可明显提高连续环形撕囊成功率,降低超声乳化手术并发症,且无明显副作用,前者廉价易得,使用效果与台盼监相同。
