Acanthamoeba keratitis has frequently been associated with contact lens use. In this study, contaminated hydrogel contact lenses of patients were subjected to disinfection by thermal hydrogen peroxide and chemical (quaternary ammonium) systems. New hydrogel contact lenses contaminated by incubation on Acanthamoeba polyphaga plates were similarly subjected to the disinfection systems described above. Thermal disinfection was universally effective in eradicating acanthamoeba, whereas hydrogen peroxide and quaternary ammonium disinfection were ineffective. Scanning electron microscope photomicrographs suggest that acanthamoeba may adhere to surfaces of hydrogel contact lenses. These findings have significant implications for soft contact lens users.
棘阿米巴角膜炎常与隐形眼镜的使用有关。在本研究中，对患者受污染的水凝胶隐形眼镜进行了热过氧化氢和化学（季铵盐）系统消毒。将在多噬棘阿米巴平板上孵育而被污染的新水凝胶隐形眼镜同样进行上述消毒系统处理。热消毒在根除棘阿米巴方面普遍有效，而过氧化氢和季铵盐消毒则无效。扫描电子显微镜照片表明棘阿米巴可能附着在水凝胶隐形眼镜表面。这些发现对软性隐形眼镜使用者具有重要意义。
