本文介绍用红色氪激光取代氩激光作虹膜切开术。治疗68眼各种闭角型青光眼的经验。操作技术:作者采用芬兰Laserlek厂产的氩-氪激光光凝器,功率为800～1000mW,光斑50μm,曝光时间为0.01～0.04秒。击射部位在12点钟距角巩膜缘1～3mm处。术前术后护理与氩激光治疗相同,包括术前用2％Pilocarpine及术后24小时内用抗生素-激素合剂滴眼。激光通过Abraham接触镜反射聚焦于虹膜上。术后2～4小时内若发现眼压增高>5mmHg,则口服 This article describes the use of red krypton laser instead of argon laser iris incision. Treatment of 68 eyes with various angle-closure glaucoma experience. Operating technology: The author uses the Finland Laserlek factory production of argon - krypton laser condenser, power 800 ~ 1000mW, spot 50μm, exposure time of 0.01 ~ 0.04 seconds. Shooting site at 12 o’clock angle from the sclera edge 1 ~ 3mm Department. Preoperative and postoperative care and argon laser treatment the same, including preoperative 2% Pilocarpine and within 24 hours after the antibiotic hormone mixture eye drops. The laser beam is focused on the iris by Abraham contact lenses. 2 ~ 4 hours after surgery if IOP increased> 5mmHg, then orally
