INTRODUCTION: This study was designed to evaluate the efficacy and safety of 3% diquafosol ophthalmic solution in dry eye patients in clinical practice. METHODS: Subjects were dry eye patients who had never used diquafosol, and observation was conducted prospectively over 2 months. The corneal and conjunctival fluorescein staining score, tear film break-up time, 12 dry eye-related subjective symptoms, patient-reported outcomes, and adverse events were investigated. RESULTS: Data were collected from 465 medical institutions for 3,196 patients. Diquafosol led to significant improvement in all subjective symptoms and objective findings (P < 0.001, paired t test). Diquafosol was effective regardless of the degree of severity according to the corneal and conjunctival fluorescein staining score or therapeutic pattern. Overall, 76.0% patients responded that their condition had improved. Adverse reactions were observed in 6.3% of patients. The major adverse reactions were eye discharge, eye irritation, and eye pain. CONCLUSION: Diquafosol was effective for various dry eye patients in clinical practice, and no significant safety-related problems occurred.
