Machmer 1971发表用玻璃体注吸切割器经睫状体扁平部作玻璃体切除术,是眼科手术史上的一大进展。我科自83年8月—85年12月,用绍兴LYQ-Ⅱ型流控式玻璃体切除器,进行闭合式玻璃体切除11例,15只眼,观察时间最长三年,最短8个月,收到较好效果,现报告如下: 一、手术方法:手术在眼内导光纤维照明下,经手术显微镜并加眼底接触镜观察进行。切除前中部玻璃体时,一般只用眼外照明,而不用显微镜和接触镜。术中应注意几点: 1.切口:玻璃体切除术均采用角膜缘后5毫米平行切口,长约3.5毫米。注意切口勿过大,扁平部色素膜切口必须大于巩膜切口,Graefe刀必须穿过玻璃体膜直插玻璃体中央部。 2.强调伤口“闭合性”:在切割头和导光纤维插入后,必须拉紧予置缝线,注意保持注吸的动态
Machmer 1971 The vitreous resection of the ciliary body flattened part with a vitreous suction cutter is a major advance in the history of ophthalmic surgery. Our department from August 1983 to December 1985, with Shaoxing LYQ-Ⅱ flow-controlled vitrectomy, closed vitrectomy in 11 cases, 15 eyes, the observation time of up to three years, the shortest of 8 months, Received good results, are as follows: First, the surgical methods: surgery in the intraocular optical fiber illumination, the operation microscope and fundus contact lens observation. Excision of the anterior vitreous, the general only with extra-ocular lighting, without the use of microscopes and contact lenses. Surgery should pay attention to several points: 1. incision: vitrectomy are used after 5 mm corneal margin parallel incision, about 3.5 mm. Note that the incision is not too large, the flat part of the cut must be greater than the scleral incision, Graefe knife must pass through the vitreous membrane directly into the center of the vitreous. 2. Stressed the wound “closed”: the cutting head and the guide fiber inserted, you must tighten the pre-set suture, pay attention to maintain the dynamic suction
