The article reviews the current literature on intraoperative techniques to properly manage anterior capsular tears during cataract surgery.
Femtosecond laser-assisted cataract surgery creates a more consistent capsulorhexis than traditional capsulotomies, but can also present with new challenges. Irregularities, like microadhesions and tags, can lead to anterior tears if not properly treated. New technology, like the Zepto (Mynosys, Fremont, CA, USA) pulse precision capsulotomy, may produce a smoother edge and reduce the incidence of capsular tears. However, there are novel rescue techniques in the case that a tear-out does occur.
Anterior capsular tears can occur at any stage of cataract surgery. The proper management of these tears will prevent them from extending into the posterior capsule and compromising the structural integrity of the capsular bag. This is essential for endocapsular placement of artificial lenses and for optimal visual outcomes for the patient.
本文回顾了当前关于白内障手术中妥善处理前囊膜撕裂的术中技术的文献。
飞秒激光辅助白内障手术比传统的囊切开术能制作出更一致的连续环形撕囊，但也会带来新的挑战。诸如微粘连和标签样不规则情况，如果处理不当，可能导致前囊膜撕裂。新技术，如Zepto（美国加利福尼亚州弗里蒙特市Mynosys公司）脉冲精准囊切开术，可能会产生更平滑的边缘并降低囊膜撕裂的发生率。然而，万一发生撕裂，也有新的补救技术。
前囊膜撕裂可发生在白内障手术的任何阶段。妥善处理这些撕裂将防止它们延伸至后囊膜并损害囊袋的结构完整性。这对于人工晶状体的囊袋内植入以及患者获得最佳视觉效果至关重要。
