目的:评估染色剂在白内障手术水分离中的作用。方法:取新鲜猪眼球87只,其中27只眼以不同浓度(0.5%、0.25%、0.125%、0.0625%)的吲哚青绿(ICG)溶液、台盼蓝(TB)(0.1%、0.05%、0.025%、0.0125%)溶液和平衡盐溶液(BSS)(各3眼)做水分离,判断染色效果;另60只眼,医生B和医生C分别以0.25%ICG、0.05%TB及BSS(各10眼)做水分离,并评价学习水分离的效果。结果:ICG、TB均能增加水分离的可视性,可视性随染色剂浓度降低逐渐变弱,ICG、TB溶液辅助水分离的难度评分和所用液体量均低于BSS组(P<0.05),ICG、TB溶液水分离的成功率高于BSS组(P<0.05)。结论:染色剂溶液辅助水分离能提高手术的可视性,并能缩短水分离技术的学习过程。
Objective: To evaluate the role of stains in the water separation of cataract surgery. Methods: Eighty - seven eyes of fresh pig were selected. Among them, 27 eyes were treated with indocyanine green (ICG) solution of different concentration (0.5%, 0.25%, 0.125%, 0.0625% , 0.025%, 0.0125%) and balanced salt solution (BSS) (3 eyes each) were separated by water to determine the staining effect. The other 60 eyes, Doctor B and Doctor C were treated with 0.25% ICG, 0.05% TB and BSS Each 10 eyes) to do water separation, and evaluate the effect of learning water separation. Results: ICG and TB both increased the visibility of water separation, and the visibility became weaker with the decrease of dye concentration. The difficulty scores and the amount of liquid used for ICG / TB solution assisted water separation were lower than those of BSS group (P <0.05 ), The success rate of ICG, TB solution water separation was higher than that of BSS group (P <0.05). CONCLUSIONS: Dye solution-assisted water separation improves the visibility of the procedure and shortens the learning process for water separation techniques.
