Abstract:
The Argentinian flag sign (AFS) is a feared complication during cataract extraction. Intralenticular pressures, especially excessive posterior pressure, have been identified as potential mechanisms for capsular stress and tearing associated with AFS. Capsular tension is created by positive intralenticular pressures, which cause the irido-lens diaphragm to move anteriorly once the manual capsulorhexis has been initiated. This tension can cause inadvertent tears that self-propagate to the lens equator, causing an AFS, among other intraoperative complications. Thus, this review highlights the importance of identifying intumescent cataracts as well as a combination of techniques to relieve intracapsular pressures needed to prevent AFS. However, some instances of anterior capsular tears are unavoidable. Therefore, focus will also be placed on techniques during cataract extraction used to manage anterior capsular tears, mitigating extension to the posterior capsule.
摘要:
阿根廷国旗标志(AFS)是白内障摘除过程中令人恐惧的并发症。透镜内压力,尤其是过度的后压力,已被确定为与AFS相关的囊应力和撕裂的潜在机制。囊袋张力是由正的晶状体内压力产生的,一旦开始手动撕囊术,这将导致虹膜透镜光阑向前移动。这种张力可能会导致无意中的眼泪自传播到镜头赤道,造成了AFS,在其他术中并发症中。因此,这篇综述强调了识别膨胀型白内障的重要性,以及减轻预防AFS所需的囊内压力的技术组合.然而,一些前囊撕裂的情况是不可避免的。因此,还将重点放在白内障摘除术期间用于治疗前囊膜撕裂的技术上,减轻对后囊的延伸。
