In order to observe the germicidal efficacy and toxicity of multi-functional contact lens cleaning-disinfection solution, suspension quantitative germicidal test, animal test and simulated field trial were used to carry out laboratory observation.

为观察全功能隐形眼镜护理液杀灭微生物效果及其毒性，采用悬液定量杀菌试验、动物试验及模拟现场等方法在实验室进行了观察。

Keratometer was used to check the corneal curve at 2 direction for 3 times to offer the mean K value, and a nearest basal lens to K value was selected as the trial lens.

步骤一：用角膜曲率仪测量角膜曲率，两个方向各测三次，取平均值，得到角膜曲率的平均K值，选取与K值接近的镜片作为试戴片。
