PURPOSE
The purpose of this study was to evaluate the contamination of used disposable soft contact lenses with Acanthamoeba.
METHODS
We evaluated 51 consecutive disposable soft contact lens wearers in a prospective study. Before their check-up visits, patients were offered a free new contact lens in exchange for donating their old one. The used contact lenses (n = 102) were then removed and placed in culture medium for Acanthamoeba. We subsequently investigated patterns of wear and hygiene habits.
RESULTS
The mean age of this population was 32.6 +/- 11.0 years. The average time of disposable soft contact lens wear was 13.7 hours per day. The contact lenses were disinfected daily with commercial solutions. Twenty-five (49.0%) subjects did not clean their lens cases properly. Acanthamoeba was not isolated from any of the 102 lenses.
CONCLUSIONS
There were no cases of Acanthamoeba contamination in a small population of disposable soft contact lens wearers who regularly disinfected their lenses with standard commercially available contact lens solutions.
目的
本研究旨在评估用过的一次性软性隐形眼镜被棘阿米巴污染的情况。
方法
在一项前瞻性研究中，我们评估了51名连续的一次性软性隐形眼镜佩戴者。在他们进行检查之前，患者可以用旧的隐形眼镜换取一副免费的新隐形眼镜。然后取出用过的隐形眼镜（n = 102），放入用于培养棘阿米巴的培养基中。随后，我们调查了佩戴模式和卫生习惯。
结果
该人群的平均年龄为32.6±11.0岁。一次性软性隐形眼镜的平均佩戴时间为每天13.7小时。隐形眼镜每天用市售溶液消毒。25名（49.0%）受试者未正确清洁其镜盒。在102只隐形眼镜中均未分离出棘阿米巴。
结论
在一小部分定期用标准市售隐形眼镜溶液消毒隐形眼镜的一次性软性隐形眼镜佩戴者中，没有棘阿米巴污染的病例。
