Capsulorhexis in white intumescent cataract is often associated with extension leading to radial tears or biradial extension "Argentinian flag sign" and associated complications. We describe a novel technique of managing this situation. Vacuum rhexis is performed with a 24 G bent cannula attached to a 10-ml syringe. The flap is lifted and then caught using 24 G cannula. The suction is manually controlled by the surgeon, and the rhexis is completed using circumferential movement. The chamber stability is well maintained as there is no leakage, and the bent tip gives excellent fulcrum for movement. The advantage of this technique is that a single port is used for maintaining the chamber stability and it needs no special surgical instruments. Vacuum rhexis is a novel surgical technique used for performing successful continuous curvilinear capsulorhexis (CCC) of adequate size in white and intumescent cataracts, with a consistent and predictable outcome.
在白色膨胀性白内障中进行囊膜环形撕囊时，常常会发生扩展，导致放射状撕裂或双放射状扩展的“阿根廷国旗征”，并伴有相关并发症。我们描述了一种处理这种情况的新技术。使用连接在 10 毫升注射器上的 24G 弯套管进行真空撕囊。提起瓣，然后用 24G 套管抓住。通过外科医生手动控制吸力，用环行运动完成撕囊。由于没有泄漏， chamber 稳定性保持良好，弯曲的尖端为运动提供了极好的支点。该技术的优点是，使用单个端口即可维持 chamber 稳定性，且不需要特殊的手术器械。真空撕囊是一种新的手术技术，用于成功地对白色膨胀性白内障进行足够大小的连续环形撕囊（CCC），具有一致且可预测的结果。
