To present the means and technique used in our Department for prevention and management of posterior capsule rupture during planned extracapsular cataract extraction.
Prospective analysis of 550 extracapsular cataract operations from October 1993 to March 1994. Our technique (a slight modification of Blumenthal's technique) included a triplanar watertight small scleral incision, a relatively large continuous curvilinear capsulorhexis, or can-opener capsulotomy, nucleus hydrodissection and hydroexpression, use of an anterior chamber maintainer and residual cortex removal through a 10 o'clock side-port corneal incision.
Best corrected postoperative visual acuity ranged from 7-10/10 in 93.45% of our cases. Posterior capsule rupture with or without vitreous loss occurred in 1.63% and 2.72% of the cases, respectively. These rates are much lower than those, observed, when we used the sclerocorneal incision and nucleus extraction with external pressure.
The combination of a triplanar watertight small scleral incision. A relatively large continuous curvilinear capsulorhexis, an anterior chamber maintainer and residual cortex aspiration through the 10 o'clock side-port corneal incision greatly reduced the posterior capsule rupture rate.
介绍我们科室在计划性囊外白内障摘除术中预防和处理后囊膜破裂所采用的方法和技术。
对1993年10月至1994年3月期间的550例囊外白内障手术进行前瞻性分析。我们的技术(对布卢门撒尔技术的轻微改良)包括三平面水密性巩膜小切口、相对较大的连续环形撕囊或开罐式截囊、核水分分离和水冲娩出、使用前房维持器以及通过10点位角膜侧切口清除残留皮质。
93.45%的病例术后最佳矫正视力达到7 - 10/10。后囊膜破裂伴或不伴玻璃体脱出分别发生在1.63%和2.72%的病例中。这些发生率远低于我们使用角巩膜切口和外部加压法进行核摘除时观察到的发生率。
三平面水密性巩膜小切口、相对较大的连续环形撕囊、前房维持器以及通过10点位角膜侧切口抽吸残留皮质的联合应用极大地降低了后囊膜破裂率。
