Management of the subluxated crystalline lens: A review

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.
