To demonstrate the use of urology retractable three-pronged grasping forceps in the removal of a large, round, and nonmagnetic intraocular foreign body (IOFB) that was difficult to remove with other surgical instruments.
Extraction of a 3.0 mm lead shot pellet embedded in vitreous hemorrhage was attempted with multiple surgical instruments including an intraocular magnet, IOFB forceps, and two tools designed for urology stone removal: a three-pronged grasping forceps and a nitinol basket extractor.
Owing to the round and smooth surface, large size, and nonmagnetic nature of the IOFB, extraction was challenging and failed with multiple other surgical instruments. The wide and secure grasp of the grasping forceps allowed for swift IOFB extraction without iatrogenic injury to the retina.
The grasping forceps offer an effective and safe method for removal of large, round, and nonmagnetic IOFBs.
展示泌尿科可伸缩三爪抓钳在移除大而圆且非磁性眼内异物（IOFB）中的应用，该异物用其他手术器械难以取出。
尝试使用多种手术器械，包括眼内磁铁、IOFB 夹和两种专为泌尿科结石取出设计的工具：三爪抓钳和镍钛诺篮提取器，来提取嵌入玻璃体积血中的 3.0 毫米铅弹丸。
由于 IOFB 的圆形和光滑表面、较大尺寸和非磁性，使用多种其他手术器械提取都具有挑战性，并且失败了。抓钳的宽大而稳固的抓握可以迅速取出 IOFB，而不会对视网膜造成医源性损伤。
抓钳为取出大而圆且非磁性 IOFB 提供了一种有效且安全的方法。
