The management of intralenticular foreign bodies (ILFBs) with or without cataract has varied from time to time in the last century. We evaluated the surgical removal of the ILFBs with cataract extraction as a single-stage procedure.
Eight consecutive cases with intralenticular foreign bodies presenting to the trauma centre at our institute, were included in the study. Planned ILFB removal with cataract extraction and IOL implantation as a single-stage procedure was done in all the patients. They were followed up from 2 months to 2 years after the surgery.
ILFBs were removed with Kelman-Mcpherson forceps in seven cases and in one it was expressed with the nucleus during extra capsular cataract extraction. Co-existent posterior capsular tears were seen in two eyes, of which only one needed a localized vitrectomy. Posterior chamber intraocular lens implantation was possible without any complication in all the cases. Postoperative uveitis seen in three cases was easily controlled with periocular steroids. Best corrected visual acuity at last examination was 6/9 or better in 7 cases and 6/12 in one case with posterior capsular opacification.
Timing and necessity of ILFB removal may be adjusted according to the foreign body characteristics and associated ocular trauma, choosing, as far as possible, the least traumatic procedure. Use of forceps rather than magnets is safer for the removal of the ILFB. Co-existent posterior capsular tears need to be anticipated and dealt with when encountered.
在上个世纪,有或无白内障的晶状体异物(ILFBs)的处理方法一直在不断变化。我们评估了将ILFBs取出与白内障摘除作为一个单阶段手术的方法。
本研究纳入了在我们研究所创伤中心连续就诊的8例晶状体异物患者。所有患者均计划将ILFBs取出与白内障摘除及人工晶状体植入作为一个单阶段手术进行。术后对他们进行了2个月至2年的随访。
7例患者使用Kelman-Mcpherson镊子取出ILFBs,1例在囊外白内障摘除时与晶状体核一起被挤出。2只眼出现了并存的后囊膜撕裂,其中只有1只眼需要进行局部玻璃体切除术。所有病例均成功植入后房型人工晶状体,无任何并发症。3例患者出现术后葡萄膜炎,经眼周注射类固醇后很容易得到控制。最后一次检查时,7例患者的最佳矫正视力为6/9或更好,1例因后囊膜混浊最佳矫正视力为6/12。
ILFBs取出的时机和必要性可根据异物特征及相关眼外伤情况进行调整,尽可能选择创伤最小的手术方式。使用镊子而非磁铁取出ILFBs更安全。需要对并存的后囊膜撕裂有所预见,并在遇到时进行处理。
