The aim of this study was to explore a new surgical method for removing magnetic intraocular foreign bodies(IOFB). We systematically reviewed 48 patients (48 affected eyes; 44 males and 4 females; aged 23-74 years, with a mean age of 44.8 ± 12.3 years) with magnetic IOFBs who were admitted to the Department of Ocular Trauma of Hebei Eye Hospital from January 2024 to June 2024. The most common cause of injury was ferrous foreign bodies resulting from working with metallic tools. Thirty-seven of the injuries were sustained in the patient's workplace, and 11 injuries occurred domestically. The patients presented to the clinic 40 min to 60 days after injury. The time from injury to surgery ranged from 1 h to 14 d. In the preoperative examinations and postoperative routine follow-ups, the basic conditions of the patients' eyes were evaluated through visual acuity examination using an international standard chart, slit lamp microscopic examination, anterior and posterior segment examinations with anterior slit lamp lenses, and intraocular pressure measurements. Before surgery, the foreign bodies were properly localized via horizontal and coronal localization CT scans, and type-B ultrasound scans were performed for patients with closed wounds. Ophthalmic magnets were used to remove magnetic IOFBs from 48 cases (48 eyes); in 44 cases, the foreign body was removed successfully during the stage I operation, representing a success rate of 91.7%. Among the included cases, 10 cases of anterior chamber IOFBs and crystalline lens IOFBs were all successfully removed during stage I surgery, for a success rate of 100%; in 38 cases of intravitreal IOFBs, 34 were successfully removed during stage I surgery via pars plana vitrectomy, and 4 cases failed to be removed in stage I surgery and were subsequently removed via stage II vitrectomy, for a stage I surgery success rate of 89.5%. Owing to their strong magnetic force, ophthalmic magnets have been demonstrated to be effective tools for the removal of magnetic IOFBs, enabling simple and time-conserving surgical procedures that are associated with less surgically induced trauma and fewer complications.
本研究的目的是探索一种去除磁性眼内异物（IOFB）的新手术方法。我们系统回顾了2024年1月至2024年6月期间河北眼科医院眼外伤科收治的48例（48只患眼；44例男性，4例女性；年龄23 - 74岁，平均年龄44.8±12.3岁）磁性IOFB患者。最常见的受伤原因是使用金属工具时产生的铁磁性异物。其中37例受伤发生在患者工作场所，11例受伤发生在家庭环境。患者在受伤后40分钟至60天前来就诊。受伤至手术的时间为1小时至14天。在术前检查和术后常规随访中，通过使用国际标准视力表进行视力检查、裂隙灯显微镜检查、使用前房裂隙灯镜片进行眼前段和眼后段检查以及测量眼压来评估患者眼睛的基本情况。手术前，通过水平和冠状位定位CT扫描对异物进行准确定位，对于闭合伤口的患者进行B型超声扫描。使用眼科磁铁从48例（48只眼）中取出磁性IOFB；44例患者在一期手术中成功取出异物，成功率为91.7%。在纳入病例中，10例前房IOFB和晶状体IOFB在一期手术中均成功取出，成功率为100%；在38例玻璃体内IOFB中，34例通过玻璃体切割术在一期手术中成功取出，4例在一期手术中未能取出，随后通过二期玻璃体切割术取出，一期手术成功率为89.5%。由于其强大的磁力，眼科磁铁已被证明是去除磁性IOFB的有效工具，能够实现简单且节省时间的手术操作，手术创伤较小且并发症较少。
