PURPOSE
To evaluate excimer laser fluence after experimentally induced changes in room temperature and relative air humidity.
METHODS
Excimer laser fluence was analyzed with a specific power meter under three different gradients of room temperature and relative air humidity as well as the reproducibility of myopic correction of -3.00 diopters in a polymethylmethacrylate plate test.
RESULTS
Under the simulated environmental conditions, no significant difference in laser energy fluence and reproduction of myopic correction was observed.
CONCLUSIONS
In a setting with controlled temperature and relative air humidity, subtle changes in environmental factors do not appear to influence laser fluence and efficacy.
目的
评估在实验诱导的室温及相对空气湿度变化后准分子激光的能量密度。
方法
使用特定功率计分析准分子激光能量密度，该分析在三种不同的室温及相对空气湿度梯度下进行，同时在聚甲基丙烯酸甲酯板测试中评估-3.00屈光度近视矫正的可重复性。
结果
在模拟环境条件下，未观察到激光能量密度及近视矫正重复性的显著差异。
结论
在温度和相对空气湿度受控的环境中，环境因素的细微变化似乎不会影响激光能量密度及疗效。
