Contact lens storage cases may harbor a variety of pathogenic organisms, and are a potential source of ocular infection. In this study, we evaluated the anti-microbial efficacy of several methods of rinsing of contact lens storage cases.
Lens cases were inoculated with Pseudomonas aeruginosa and then 1) rinsed with hot tap water and closed without drying, 2) rinsed with hot tap water followed by air drying, 3) rinsed with 3% hydrogen peroxide followed by air drying, or 4) left closed and undisturbed (control condition). After 24 hours, the cases were cultured to determine the rate of disinfection.
The hydrogen peroxide rinse was the most effective (99.5 percent of cases disinfected), followed by hot water with air drying (94.7 percent) and hot water without drying (51.1 percent). Significant residual hydrogen peroxide was detected in the cases rinsed with peroxide.
Therefore, we recommend that patients be instructed to rinse their cases with hot water and allow them to air dry after use, as well as replace their cases on a regular basis.
隐形眼镜储存盒可能藏有多种致病微生物，是眼部感染的一个潜在源头。在本研究中，我们评估了几种清洗隐形眼镜储存盒方法的抗菌效果。
将铜绿假单胞菌接种到镜片盒中，然后：1）用热水冲洗后不擦干直接关闭；2）用热水冲洗后风干；3）用3%过氧化氢冲洗后风干；或4）保持关闭且不做处理（对照情况）。24小时后，对镜片盒进行培养以确定消毒率。
用过氧化氢冲洗最有效（99.5%的镜片盒消毒），其次是热水冲洗后风干（94.7%）和热水冲洗后不擦干（51.1%）。在用过氧化物冲洗的镜片盒中检测到有大量残留过氧化氢。
因此，我们建议指导患者在使用后用热水冲洗镜片盒并使其风干，以及定期更换镜片盒。
