A prospective study of 24 contact lens patients with culture- or histopathology-proven microbial keratitis was performed between July and December 1987 to determine associated lens care practices and patterns of lens care product contamination. A questionnaire was used to document methods of lens care. Bacterial cultures were performed on all available contact lenses, lens cases, and solutions (including saline, disinfectant, daily cleaner and wetting agents), in addition to standard smears and cultures of the corneal ulcer. Failure to follow standard recommendations regarding contact lens care was widespread (21 of 24, 88%). In the majority of patients (20 of 24, 83%) bacterial contamination of the contact lens, case, and/or solutions was present. Almost two-thirds (15 of 24, 62%) of patients used solutions that were more than 3 months old. Cosmetic extended wear lens patients were most likely (7 of 8, 88%) to use solutions that were more than 3 months old and very likely (6 of 8, 85%) to have contaminated solutions. Efforts to improve lens care and decrease lens product contamination are necessary to prevent contact lens associated corneal ulcers.
1987年7月至12月期间，对24例经培养或组织病理学证实患有微生物性角膜炎的隐形眼镜佩戴者进行了一项前瞻性研究，以确定相关的镜片护理习惯和镜片护理产品污染模式。使用问卷调查来记录镜片护理方法。除了对角膜溃疡进行标准涂片和培养外，还对所有可用的隐形眼镜、镜盒和护理液（包括生理盐水、消毒剂、日常清洁剂和润眼液）进行了细菌培养。不遵循隐形眼镜护理标准建议的情况很普遍（24例中有21例，占88%）。大多数患者（24例中有20例，占83%）的隐形眼镜、镜盒和/或护理液存在细菌污染。近三分之二（24例中有15例，占62%）的患者使用超过3个月的护理液。使用美容性长戴型隐形眼镜的患者最有可能（8例中有7例，占88%）使用超过3个月的护理液，并且很有可能（8例中有6例，占85%）使用被污染的护理液。为预防与隐形眼镜相关的角膜溃疡，有必要努力改善镜片护理并减少镜片产品污染。
