CORGI Trial Summary

The purpose of this study is to refit habitual wearers of daily disposable contact lenses who currently experience symptoms of dry eye and discomfort during lens wear with a different type of daily disposable contact lens. Ocular signs and symptoms of dry eye will be assessed following the guidelines outlined by the Tear Film and Ocular Surface Society (TFOS) in the Dry Eye Workshop II (DEWS II). The performance of the habitual contact lenses and the study lenses will be determined using different optometric assessments. Study lenses will be worn for one month following a daily disposable wear schedule.
