PURPOSE
The purpose of this study was to determine the changes in bacterial adhesion resulting from air-drying soft contact lenses.
METHODS
An in vitro study was conducted on four sets of identical, unworn etafilcon A soft contact lenses, air-dried for varying periods of time. These lenses were placed in a bacterial suspension, rinsed, ground, and plated in order to determine bacterial adhesion.
RESULTS
The increased bacterial adhesion to these high water content, ionic lenses was statistically significant following five minutes of drying. Reversal of the effect was noted after rehydration.
CONCLUSIONS
Soft contact lens drying results in increased bacterial adhesion.
目的
本研究的目的是确定空气干燥软性隐形眼镜后细菌黏附的变化。
方法
对四组相同的、未佩戴过的依他氟康A软性隐形眼镜进行体外研究，将其空气干燥不同时间。将这些镜片置于细菌悬液中，冲洗、研磨并接种，以确定细菌黏附情况。
结果
干燥五分钟后，这些高含水量离子型镜片上细菌黏附增加具有统计学意义。复水后该效应逆转。
结论
软性隐形眼镜干燥会导致细菌黏附增加。
