We report 2 cases illustrating the use of a new technique to manage vitreous loss during phacoemulsification, which we have termed 'trimanual' anterior vitrectomy. In each case, after recognizing posterior capsule tear, the remaining nuclear pieces were removed with low-parameter phacoemulsification. The remaining cortical material was then removed using bimanual irrigation and aspiration handpieces while the assistant surgeon inserted the vitrectomy probe through a separate 1-mm limbal incision. The vitrectomy probe was held below the plane of the posterior capsule tear, used to cut the vitreous and to provide a mechanical blockade to potentially descending lens material. While this technique involves the potentially awkward simultaneous use of 3 intraocular instruments, we believe that there are several advantages over standard bimanual anterior vitrectomy.
我们报告2例病例,阐述一种用于处理白内障超声乳化术中玻璃体丢失的新技术,我们将其称为“三手法”前部玻璃体切除术。在每例病例中,识别出后囊膜破裂后,用低参数超声乳化术移除剩余的核块。然后使用双手动灌注抽吸手柄移除剩余的皮质物质,同时助手医师通过单独的1毫米角膜缘切口插入玻璃体切割探头。玻璃体切割探头置于后囊膜破裂平面下方,用于切割玻璃体,并为可能下沉的晶状体物质提供机械性阻挡。虽然该技术涉及同时使用3种眼内器械,可能操作不便,但我们认为与标准双手动前部玻璃体切除术相比有几个优点。
