Wireless Micropump in Dry Eye Patients

Summary

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.
