Intumescent cataract can be a challenge even for an experienced surgeon, particularly for creating a continuous curvilinear capsulorhexis (CCC) because of increased endolenticular pressure. CCC in white intumescent cataract is associated with increased risk of extension of rhexis margin leading to radial tear or biradial extension causing "Argentinian flag sign" and associated complications. We describe a novel technique for CCC, in which we manipulate the vector forces acting in creating a capsulorhexis. After making a mini CCC, a flap is raised and then inverted under the rhexis margin and CCC is done by keeping the flap inverted using shearing and tearing forces, keeping the direction of force down and toward the center in a curvilinear fashion. It is a new surgical technique to perform a successful and safer CCC in intumescent cataract with consistent outcome.
膨胀性白内障即使对于经验丰富的外科医生来说也是一个挑战，特别是在创建连续曲线性囊膜环形撕囊（CCC）时，因为晶状体内部压力增加。由于内囊张力增加，白色膨胀性白内障的 CCC 与撕囊边缘扩展的风险增加相关，导致放射状撕裂或双放射状扩展，从而出现“阿根廷国旗征”和相关并发症。我们描述了一种用于 CCC 的新技术，我们在创建囊膜环形撕囊时操纵作用于其上的向量力。在进行小的 CCC 后，掀起一个瓣，然后在撕囊边缘下翻转，然后通过使用剪切和撕裂力保持瓣翻转来完成 CCC，使力的方向向下并沿曲线向中心方向。这是一种在膨胀性白内障中成功、更安全地进行 CCC 的新技术，结果一致。
