Achieving a complete uniform capsulorhexis in an intumescent cataract is perhaps the most crucial and challenging step for surgeons. Star CanVac CCC is a new manual technique for creating a continuous curvilinear capsulorhexis (CCC) in intumescent total cataracts. Small centripetal tears in the shape of a star are created in the center of the anterior lens capsule by using a 26-G cystotome. This allows equal distribution of forces secondary to increased intralenticular pressure, thereby avoiding unidirectional or bidirectional tear extension. Subsequently, a 25-G flat-tipped fine cannula connected to a syringe is used to hold the free capsular flap. The piston of the syringe is withdrawn to create a stable suction pressure, and the rhexis is completed without withdrawing the instrument from the anterior chamber. Our technique is safe, affordable, and an alternative method to routine CCC or expensive techniques such as Femto or Zepto capsulotomy for white intumescent cataracts.
在膨胀性白内障中实现完整均匀的撕囊是外科医生最关键和最具挑战性的步骤之一。Star CanVac CCC 是一种新的手动技术，用于在膨胀性全白内障中创建连续曲线撕囊（CCC）。在前晶状体囊的中心使用 26-G 囊切刀创建小的向心性星形撕裂，从而在增加的晶状体压力下实现力量的均匀分布，从而避免单向或双向撕裂扩展。随后，使用连接到注射器的 25-G 平头细套管来固定游离的囊瓣。将注射器的活塞抽出以产生稳定的吸力，而无需将器械从前房撤出即可完成撕囊。我们的技术安全、经济实惠，是白色膨胀性白内障常规 CCC 或昂贵技术（如 Femto 或 Zepto 囊切开术）的替代方法。
