Primary outcomePrimary: Contact Lens Dry Eye Questionnaire (CLDEQ-8) Score in the Study Eye — 15.3; 17.2 score on a scale — p=0.116
Summary
This study will evaluate the increase in comfort and comfortable contact lens (CL) wear time associated with application of TrueTear (active intranasal neurostimulation) compared with application of TrueTear sham control (intranasal application which is not electrically active) in symptomatic CL wearers.
