近年来,白内障囊外摘出的数量不断增加,促使人们注意后囊膜混浊的处理问题。Thompson(1983)介绍用一脉冲钕-钇铝石榴石(YAG)激光器作后囊膜打孔的方法,此法无损伤性,但其安全性及效果仍有待进一步确定。作者就此方法的短期效果分析,强调其潜在的早期并发症。本文包括49眼白内障囊外摘出术后以钕-YAG激光作后囊膜打孔术的病例。其中27眼置入后房型人工晶体,1眼为前房型,2眼为虹膜面型,其余19眼未置入人工晶体。手术后1～54个月发生后囊膜混浊,在白内障摘出后平均21.4个月作后囊膜打孔术。12例使用Abraham接触镜。一般作6～107个击射点,(平均36个击射点)在后囊膜上造成一个开口。激光能量一般为
In recent years, the number of extracapsular extracapsular cataracts continues to increase, prompting attention to the treatment of posterior capsular opacity. Thompson (1983) introduced a pulsed neodymium-yttrium aluminum garnet (YAG) lasers for posterior capsular membrane drilling method, this method without damage, but its safety and efficacy remains to be determined. The author analyzes the short-term effects of this method, emphasizing its potential for early complications. This article includes 49 cases of extracapsular cataract extracapsular neodymium-YAG laser posterior capsule perforation cases. Among them, 27 eyes were treated with posterior chamber intraocular lens (IOL), one was anterior chamber type, the other two eyes were iris surface type. The remaining 19 eyes were not placed intraocular lens. Posterior capsular opacification occurs 1 to 54 months after surgery, and an average of 21.4 months after posterior cataract extraction for posterior capsule perforation. Twelve patients used Abraham contact lenses. Typically 6 to 107 shot points (an average of 36 shots) create an opening in the posterior capsule. Laser energy is generally
