Intraocular lenses removed because of recurrent episodes of intraocular inflammation showed bacteria adhering to the prosthesis. Infections localized to areas around intraocular lenses have been reported in the literature. Two such infections and an in vitro study of bacterial adherence to implant surfaces are reported. Adherent bacteria were found to be more numerous on the polypropylene haptic than on the polymethylmethacrylate optic in both in vitro and in vivo cases. We suggest that the intraocular lens becomes contaminated with commensal organisms of low virulence during insertion into the eye, and that these organisms are the source of the inflammatory episodes. Experiments show that lenses as supplied are sterile and that in vitro bacteria adhere preferentially to the haptic.
因反复出现眼内炎症而被摘除的人工晶状体显示有细菌附着在假体上。文献中已报道过局限于人工晶状体周围区域的感染。本文报道了两例此类感染以及一项关于细菌在植入物表面黏附的体外研究。在体外和体内病例中均发现，聚丙烯袢上附着的细菌比聚甲基丙烯酸甲酯光学部上的更多。我们认为，人工晶状体在植入眼内过程中被低毒力的共生菌污染，这些细菌是炎症发作的根源。实验表明，所供应的晶状体是无菌的，且体外细菌优先黏附于袢上。
