The Q-switched Nd: YAG laser was used to cut vitreous traction bands in 20 eyes with an effective rate of 85%. The pulse energy ranged from 2.8-8.7mJ, and the total energy required was 196 +/- 155.3mJ. The distance of the laser beam focus to retinal surface was 3.7 +/- 2mm. Nd: YAG vitreolysis is an effective means in releasing traction bands and membranes in the posterior segment of the eye. Adaptation of a proper contact lens and optimal strength of energy with accurate focussing are conducive to increased efficacy and avoidance of retinal injury.
采用调Q钕:钇铝石榴石激光切割20只眼中的玻璃体牵引带，有效率为85%。脉冲能量范围为2.8 - 8.7mJ，所需总能量为196±155.3mJ。激光束焦点到视网膜表面的距离为3.7±2mm。钕:钇铝石榴石玻璃体溶解术是松解眼后段牵引带和膜的有效方法。适配合适的接触镜以及精确聚焦的最佳能量强度有助于提高疗效并避免视网膜损伤。
