The purpose of this study is to carry out a trial to get more convincing and valuable results
of the wireless micropump in dry eye patients and compare the outcomes before and after eye
drops usage. The investigators hope to investigate the micropump comprehensively, including
the comparison of tear film break-up time, corneal epithelium defect percentage, and tear
film thickness. To meet the demands of a trial, all the examination equipment should be the
same for each patient, and this will limit the variations within a study.
