1993年9月至1994年3月,我们对53例(53只眼)现代白内障囊外摘除并后房型人工晶体囊袋内植入术后的眼压进行了观察.现报告如下.1 资料与方法1.1 一般资料 男21例,女32例,年龄47～78(平均65)岁,均为老年白内障患者.所有病例均无青光眼、葡萄膜炎及其它眼病史.以入院体检所测眼压作为术前眼压,均不超过2.74kPa.1.2 手术方法 所有手术均在双人双目手术显微镜下进行,并由同一术者操作.术前一小时用0.25%托吡卡胺滴眼液散瞳.以2%利多卡因加少许0.1%肾上腺素分别作球后、眼轮匝肌和局部麻醉,按摩眼球10分钟后用缝线开睑,作上直肌固定缝线.按现代白内障囊外摘除手术方法,分别作球结膜、角巩膜缘切开,用5号针头做成的截囊针行开罐式截囊,娩出晶体核,角巩膜缘切口作三针间断缝合,冲吸净晶体皮质,前房及晶体
From September 1993 to March 1994, we observed the intraocular pressure (IOP) of 53 cases (53 eyes) of extracapsular cataract extraction and intraocular lens implantation in posterior chamber intraocular lens Methods 1.1 The general information of 21 males and 32 females, aged 47 to 78 (average 65) years old, are elderly patients with cataract .All cases without glaucoma, uveitis and other eye disease history to intraocular pressure measured as the physical examination as Preoperative intraocular pressure, no more than 2.74kPa.1.2 Surgical methods All operations were performed under a double binocular surgical microscope, operated by the same surgeon .One hour preoperatively with 0.25% tropicamide eye drops mydriasis. To 2% lidocaine plus a little 0.1% epinephrine respectively for the ball, the orbicularis oculi muscle and local anesthesia, eye massage after 10 minutes with a suture to open the eyelid for upper rectus fixed suture. According to the modern extracapsular cataract extraction Surgical methods, respectively, for the ball conjunctiva, angle scleral margin incision, made with a No. 5 needles dredging needle open cans capsulotomy, delivered crystal nucleus, limbal incision for three-pin intermittent suture, flushing the net cortical cortex , Anterior chamber and crystal
