[Q-switched Nd:YAG laser surgery on vitreous traction bands].
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.
