Cataract surgery for the subluxated crystalline lens is challenging. A thorough preoperative evaluation is important to determine the appropriate surgical approach for lens removal and the subsequent technique of intraocular lens placement. Important considerations include the extent and location of zonular weakness, and whether the zonular deficiency is caused by a static or progressive disease. The capsular bag should be preserved where possible. Creating a good-sized and centred continuous curvilinear capsulorhexis is crucial to facilitate the use of capsular retractors and capsular tension devices, which provide capsular stability. Nucleus sculpting and rotation should be minimised to reduce zonular stress. Being cognisant of the possible intraoperative complications that may occur at each stage of the surgery and knowing how to reduce the risk of these complications occurring will enable surgeons to perform safe cataract surgery in these complex cases.

半脱位晶状体的管理：综述

半脱位晶状体的白内障手术具有挑战性。彻底的术前评估对于确定合适的晶状体摘除手术方法和随后的人工晶状体放置技术非常重要。重要的考虑因素包括小带肌无力的程度和位置，以及小带肌无力是由静态还是进行性疾病引起的。尽可能保留囊袋。创建一个大小合适且居中的连续曲线撕囊对于促进使用提供囊稳定性的囊牵开器和囊张力装置至关重要。应尽量减少核雕刻和旋转以减少小带应力。
