Posterior polar cataracts present special challenges to the cataract surgeon. These are often associated with weakness/dehiscence of the posterior capsule and thus have a higher rate of intraoperative posterior capsule rupture. The surgeon needs to adhere to special surgical strategies to minimize the risk of a posterior capsule rupture. These include, adhering to the principles of closed chamber technique, avoiding hydrodissection - instead performing 'inside-out' hydrodelineation and using modest to low phaco parameters and reducing these stepwise. This article provides important pearls on how to approach a posterior polar cataract.
后极性白内障给白内障手术医生带来了特殊的挑战。这些白内障常与后囊膜的薄弱/裂开相关,因此术中后囊膜破裂的发生率较高。手术医生需要遵循特殊的手术策略,以将后囊膜破裂的风险降至最低。这些策略包括,坚持闭合式手术技术原则,避免水分离——改为进行“由内向外”的水分层,使用适度至较低的超声乳化参数并逐步降低这些参数。本文提供了关于如何处理后极性白内障的重要经验。
