The conjunctival cytological profiles of asymptomatic healthy contact lens wearers are described. An impression biopsy technique (5 h after insertion of contact lenses) was used. Significantly higher cell counts (neutrophils and lymphocytes) were found amongst the soft lens wearers', biopsies compared to hard lens wearers' biopsies or control subjects' biopsies. It is postulated that conjunctival cytological examination may reveal early, subclinical, cytotoxic effects attributable to the preservatives and chelating agents in soft contact lens care systems.
描述了无症状健康隐形眼镜佩戴者的结膜细胞学特征。采用了一种印片活检技术（隐形眼镜插入后5小时）。与硬性隐形眼镜佩戴者的活检或对照受试者的活检相比，软性隐形眼镜佩戴者的活检中发现细胞计数（中性粒细胞和淋巴细胞）显著更高。据推测，结膜细胞学检查可能揭示软性隐形眼镜护理系统中防腐剂和螯合剂所致的早期亚临床细胞毒性作用。
