Optimal fixation and position of an intraocular lens (IOL) is achieved when it is located in the capsular bag. A peripheral tear from the central opening to the lens periphery is associated with a high incidence of dislocation of at least one loop from within the capsular bag and lens decentration. A central round continuous capsulectomy (capsulorhexis), within the zonule-free area, provides long-term and balanced IOL fixation. To perform a well-controlled capsulectomy, a deep and stable anterior chamber should be maintained throughout the surgery. This is achieved by using a continuous anterior chamber maintainer that regulates the pressure in the anterior chamber. This paper reviews the clinical anatomical guidelines of the lens capsule and the anterior chamber and presents the authors' preferred technique for optimal anterior capsulectomy.
当人工晶状体（IOL）位于囊袋内时，可实现其最佳固定和定位。从中央开口至晶状体周边的周边撕裂与囊袋内至少一个袢脱位及晶状体偏心的高发生率相关。在无晶状体悬韧带区域内进行中央圆形连续囊膜切除术（撕囊）可提供长期且平衡的IOL固定。为了进行良好控制的囊膜切除术，在整个手术过程中应保持深而稳定的前房。这可通过使用调节前房压力的连续前房维持器来实现。本文回顾了晶状体囊膜和前房的临床解剖学指南，并介绍了作者首选的最佳前囊膜切除术技术。
