To describe a novel technique to use the NGage® Nitinol Stone Extractor for large IOFB extraction.
We conducted a retrospective case series study by reviewing the data of 4 eyes with retained large IOFB extracted with the use of the NGage® Nitinol Stone Extractor. The study was conducted in a single tertiary referral center on four eyes of four patients with large retained IOFB. Studied eyes were treated by pars plana vitrectomy (PPV) and IOFB extraction by using the NGage® Nitinol Stone Extractor through a limbal incision.
Four eyes of four male patients with large Retained IOFB were included in the study. The nature of the IOFB was metallic in 2 eyes, glass in 1 eye or ceramic 1 eye. All the IOFB were removed from a limbal wound. Silicone oil tamponade was required in 3 eyes. Two eyes required reoperation. At 6 months postoperative, the final visual acuity using Snellen chart ranged between PL and 0.1.
The NGage® Nitinol Stone Extractor can be a useful tool for the extraction of the large retained IOFB.
描述一种使用 NGage® Nitinol 取石器提取大 IOFB 的新技术。
我们通过回顾使用 NGage® Nitinol 取石器提取大 IOFB 的 4 只眼的数据进行了回顾性病例系列研究。该研究在一家三级转诊中心的 4 只眼中的 4 例患者进行，对大的 IOFB 进行标准经睫状体平坦部玻璃体切除术（PPV）和 NGage® Nitinol 取石器提取。
本研究纳入了 4 例男性大 IOFB 残留患者的 4 只眼。2 只眼的 IOFB 为金属性，1 只眼为玻璃性，1 只眼为陶瓷性。所有 IOFB 均从角巩膜缘伤口取出。3 只眼需要硅油填塞。2 只眼需要再次手术。术后 6 个月，使用 Snellen 图表的最终视力范围在 PL 到 0.1 之间。
NGage® Nitinol 取石器可以成为提取大 IOFB 的有用工具。
