Phacoemulsification (phaco) is an established procedure for cataract extraction and has undergone a significant advances in techniques, machines and phaco tips. The Aspiration Bypass System (ABS) phaco tip was introduced for phacoemulsification in 1998. The ABS tip allows fluid to be drawn through the opening when the phaco tip is occluded by nuclear material. The ABS tip allowed the safe use of high vacuum and flow rates and improved chamber stability by decreasing surge and therefore reducing intraoperative complications. To date, no disadvantages of ABS tips have been reported. We report a unique case of an intraoperative break of an ABS phaco tip during routine cataract surgery.
超声乳化白内障吸除术是一种成熟的白内障摘除手术，在技术、设备和超声乳化针头方面都取得了重大进展。1998年，用于超声乳化的抽吸旁路系统（ABS）针头问世。当超声乳化针头被核物质阻塞时，ABS针头可使液体从开口处吸出。ABS针头允许安全使用高真空和流速，并通过减少波动来提高前房稳定性，从而减少术中并发症。迄今为止，尚未有关于ABS针头缺点的报道。我们报告了一例在常规白内障手术中ABS超声乳化针头术中断裂的罕见病例。
