本文比较了白内障囊外摘出术后24小时,碳酰胆碱和乙酰胆碱对眼压的作用,表明术中前房注入碳酰胆碱对术后眼压的控制较乙酰胆碱强,建议术中缩瞳和预防术后眼压升高选用碳酰胆碱。材料与方法:将60例准备作常规白内障囊外摘出术联合后房型人工晶体植入术的病人随机分成3组:①碳酰胆碱组,②乙酰胆碱组,③0.5%平衡盐溶液组(对照组)。每组20人, This article compares the effect of carbachol and acetylcholine on intraocular pressure at 24 hours after extracapsular cataract extraction, indicating that intraoperative anterior chamber infusion of carbachol is more effective than acetylcholine in controlling postoperative IOP, And prevention of postoperative intraocular pressure increased choice of carbachol. Materials and Methods: Sixty patients scheduled for extracapsular cataract extraction combined with posterior chamber intraocular lens implantation were randomly divided into three groups: ① carbachol group, ② acetylcholine group, ③0.5% balanced salt solution group ( Control group). Each group of 20 people,
