We report three cases of Stenotrophomonas maltophilia endophthalmitis after uneventful extracapsular cataract extraction with intraocular lens implantation-related to surgical equipment contamination.
All patients developed acute, culture-positive endophthalmitis in a period ranging from 2 to 13 days. Cultures from vitreous tap, as well as those obtained from the hand-piece of the irrigation-aspiration system, revealed S. maltophilia as the causing infectious agent. All patients received intravitreal antibiotic treatment as initial therapy, nevertheless, visual disturbance continued to be present, hence pars plana vitrectomy was required.
Contamination of surgical-reusable equipment should be considered in addition to the well-known risk factors associated with development of endophthalmitis by S. maltophilia.
我们报告3例嗜麦芽窄食单胞菌性眼内炎病例，这些病例发生在白内障囊外摘除联合人工晶状体植入术后，且手术过程顺利，病因与手术设备污染有关。
所有患者均在2至13天内发生急性、培养阳性的眼内炎。玻璃体穿刺液培养以及从灌吸系统手持件获得的培养物均显示嗜麦芽窄食单胞菌为致病感染源。所有患者均接受玻璃体内抗生素治疗作为初始治疗，但视力障碍仍持续存在，因此需要进行玻璃体切除术。
除了与嗜麦芽窄食单胞菌性眼内炎发生相关的众所周知的危险因素外，还应考虑手术可重复使用设备的污染问题。
