后囊膜混浊的先天性白内障术中的连续线形撕后囊术

目的研究后囊膜混浊的先天性白内障摘除术后的后囊膜处理方法。方法在３２只眼后囊膜混浊的先天性白内障中，摘除白内障及植入人工晶体后于后囊膜的旁中心作一穿刺孔，然后向后囊膜与玻璃体前界膜的间隙注入Ｈｅａｌｏｎ，再沿后囊膜穿刺孔边缘线形撕开一个直径约４ｍｍ的圆孔。结果全部术眼后囊膜中央有一透明裂孔，２只眼玻璃体溢出，术后未见人工晶体移位。结论连续线形撕后囊术可使后囊膜混浊的先天性白内障获得视轴透明区，并保持周边囊袋的完整性。

Posterior continuous curvilinear capsulorhixis in congenital cataract with opaque posterior capsule

Objictive To study the management of the opacified posterior lens capsule in congenital cataract extraction with intraocular lens (IOL) implantation.Methods Posterior continuous curvilinear capsulorhexis was performed on 36 eyes of congenital cataract with opaque posterior capsule.After the removal of cortical material and implantation of IOL,a perforation was made near the center of the posterior capsule through the equator of IOL,Healon was directed toward the opening and injected into the interspace between the posterior capsule and the anterior limiting membrane of the vitreous,and a 4 mm diameter posterior capsulorhexis was performed with aforceps.Results All the eyes achieved a clear visual axis.There was vitreous prolapse in two eyes.IOL decentration did not occur in any case .Conclusion Posterior continuos capsulorhexis could remain the integrity of the peripheral capsular bag with aclear visual axis in the eye with congenital cataract and an opaque posterior capsule.
