儿童外伤性白内障摘除后囊混浊发病率高，发生原因认为是儿童晶状体上皮细胞增生活跃，以后囊膜为支架增生迁徙所致。将晶体皮质清除及切除部分后囊膜是防止后囊混浊的关键。我们在手术中用玻璃体切割器清除晶状体残留皮质及在视轴区切除约4mm近圆形的后囊膜，再将人工晶体植入 Children traumatic cataract removal of posterior capsule opacity incidence is high, the reason is that children with lens epithelial cell hyperplasia, after the cyst is due to migration of stent hyperplasia. The crystal cortex removal and resection of the posterior capsule is the key to prevent posterior capsule opacity. We used vitrectomy to clear the residual cortex of the lens during surgery and resect approximately 4 mm of a nearly circular posterior capsule in the optic axis and implant the intraocular lens
