One hundred sterile intraocular lenses were placed on the external eye of 50 patients during cataract surgery. Half of the specimens were cultured for bacteria, the other half were examined under the light microscope after fixing and staining. A bacterial contamination rate of 26% was recorded. This is significantly higher than that found in conjunctival swabs (6%) or irrigation specimens (8%) taken at the same time, and higher than that recorded in a group of control lenses (15.2%) exposed to operating theatre air alone. We propose that intraocular lenses contaminated with viable bacteria may be implanted into the eye and thereby account for some cases of postoperative uveitis in the pseudophakic eye.
在白内障手术期间，将100个无菌人工晶状体放置在50名患者的眼球表面。一半样本进行细菌培养，另一半在固定和染色后进行光学显微镜检查。记录的细菌污染率为26%。这显著高于同时采集的结膜拭子（6%）或冲洗样本（8%）中的污染率，也高于仅暴露于手术室空气的一组对照晶状体（15.2%）的污染率。我们认为，被活菌污染的人工晶状体可能会被植入眼内，从而导致一些假晶状体眼术后葡萄膜炎病例的发生。
