Tear Film Stability and Improvement of Asthenopia: Efficacy Observation of 0.05% Cyclosporine in Dry Eye Patients With Short BUT

Brief Summary
At present, research on cyclosporine mainly focuses on patients with moderate to severe dry eye. Based on the importance of the vicious cycle of inflammation in the pathogenesis of dry eye and the mechanism of cyclosporine, investigators believe that it may also have therapeutic effects in patients with mild to moderate dry eye, and may have certain advantages compared to traditional artificial tear therapy. In summary, this study intends to use a randomized, double-blind, parallel controlled trial to evaluate the therapeutic efficacy and safety of 0.05% cyclosporine eye drops in patients with mild to moderate dry eyes.
