A Single Center, Randomized, Controlled, Single-Masked, Cross-Over Clinical Pilot Study to Evaluate the Reduction in the Exacerbation of the Symptoms of Dry Eye Upon Exposure to a Controlled Adverse Environment (CAESM) With Treatment by the Oculeve Nasal Lacrimal TENS Unit

Change From Pre-Application to Post-Application in the Ora Calibra Ocular Discomfort Scale (ODS) Score

时间窗: Pre-application to Post-application on Day 0

The participant graded their eye discomfort prior to CAE entry, during CAE exposure to threshold, then starting 1 minute after treatment application every 5 minutes in each eye separately using the Ora Calibra ODS where: 0=no discomfort to 4=constant discomfort. Data from the analysis eye was used to determine effectiveness. The analysis eye was defined as the first eye that reached the threshold and resulted in the device application. If both eyes reached the threshold at the same time point, the analysis eye was the eye with the lowest baseline Schirmer test score (a test to determine if the eye produces enough tears to keep it moist; \>10 mm is normal) or, if the Schirmer test scores were equal, the right eye. A negative change from Baseline indicates improvement.
