摘要
利用人工泪液浸泡镜片．模拟蛋白吸附．采用紫外分光光度计在波长280 nm处测试经护理液洗脱的蛋白质的吸光度, 计算蛋白质含量。测试除蛋白护理液对软性角膜接触镜上的蛋白质沉淀的洗脱效果。结果除蛋白含量的测试结果具有重复性。该试验方法可以对除蛋白护理液的洗脱率效果进行评价,但尚需完善．
Objective： Testing the protein-removing effect of the protein-removing care solution on the protein precipitation of the soft contact lenses. Method： Soak the lenses into the artificial-tears to simulate the protein absorption, test the absorbency of cleaned protein at the wavelength of 280 nm by UV spectrophotometer, and compute the percentage of protein. Result： Testing results of the percentage of the cleaned protein are repeatable. Conclusion： This experimental method can be used to evaluate the cleaning effect of the protein-removing care solution, but still needs much improvements.
