Management of intralenticular foreign bodies (ILFBs) is controversial. Correlation between visual outcome, foreign body characteristics, the need for surgical intervention, and the choice of surgical technique are not well established. We report five cases of traumatic ILFBs all managed surgically. Three ILFBs were metal, one was presumably also metal, and one was wood. We chose to proceed with foreign body removal and simultaneous cataract extraction with intraocular lens implantation as a single-staged procedure in four cases. In one case of planned extracapsular cataract extraction, a foreign body was identified only after the expressed nucleus was sent for pathological examination. Visual outcomes were 20/30 or greater in all cases at 5 to 18 month follow up.
晶状体异物(ILFBs)的处理存在争议。视觉预后、异物特征、手术干预的必要性以及手术技术的选择之间的相关性尚未明确。我们报告了5例外伤性ILFBs均接受了手术治疗。3个ILFBs为金属异物,1个可能也是金属异物,1个为木质异物。4例患者我们选择将异物取出与白内障摘除及人工晶状体植入作为一期手术同时进行。在1例计划行囊外白内障摘除术的患者中,仅在将挤出的晶状体核送去做病理检查后才发现异物。随访5至18个月时,所有病例的视力均达到20/30或更好。
