Over a 21-month period, we treated corneal ulcers in 11 patients using daily-wear contact lenses and 29 patients using extended-wear contact lenses. Since more patients use daily-wear than extended-wear lenses, this suggests that patients using extended-wear lenses are at greater risk for the development of corneal ulcers. Positive bacterial cultures were obtained from the corneal scrapings of nine of 11 patients using daily-wear lenses and 20 of 29 patients using extended-wear lenses. In the daily-wear group, all 11 patients failed to exercise satisfactory care in using and disinfecting their contact lenses: three did not wash their hands before manipulating the contact lenses, eight wore them overnight, two did not use any disinfecting system, and four had contaminated contact lens cases, solutions, or drops. In the extended-wear group, 17 patients failed to exercise satisfactory care in using and disinfecting their contact lenses: 12 had contaminated contact lens care systems, two did not use any disinfection system, five reported not washing their hands before contact lens manipulation, and two disinfected their contact lenses at intervals of more than a month. We were unable to identify any defect in the way 12 patients took care of their extended-wear lenses, suggesting that there may be a problem with these contact lenses even when care is satisfactory.
在21个月的时间里，我们对11名使用日戴型隐形眼镜的患者和29名使用长戴型隐形眼镜的患者进行了角膜溃疡治疗。由于使用日戴型隐形眼镜的患者比长戴型隐形眼镜的患者多，这表明使用长戴型隐形眼镜的患者发生角膜溃疡的风险更高。在使用日戴型隐形眼镜的11名患者中，有9名患者的角膜刮片中细菌培养呈阳性；在使用长戴型隐形眼镜的29名患者中，有20名患者的角膜刮片中细菌培养呈阳性。在日戴型隐形眼镜组中，所有11名患者在使用和消毒隐形眼镜时都没有进行令人满意的护理：3名患者在操作隐形眼镜前不洗手，8名患者过夜佩戴，2名患者不使用任何消毒系统，4名患者的隐形眼镜盒、护理液或滴眼液受到污染。在长戴型隐形眼镜组中，17名患者在使用和消毒隐形眼镜时没有进行令人满意的护理：12名患者的隐形眼镜护理系统受到污染，2名患者不使用任何消毒系统，5名患者报告在操作隐形眼镜前不洗手，2名患者消毒隐形眼镜的间隔时间超过一个月。我们无法确定12名患者护理长戴型隐形眼镜的方式存在任何缺陷，这表明即使护理得当，这些隐形眼镜可能也存在问题。
