About this trial
This is an interventional other trial for Dry Eye focused on measuring Dry Eye Disease
Eligibility Criteria
Inclusion Criteria:
- Mild to severe dry eye disease
- Have not worn contact lenses for at least seven days prior to the Screening Visit and willing to forego the use of contact lenses for the duration of the study
- Literate, able to speak English or Spanish, and able to complete questionnaires independently
Exclusion Criteria:
- Previously used the Intranasal Neurostimulator at any time
- Used commercial lid hygiene product within 14 days of the Screening Visit or plan to use at any time during the study
- Chronic or recurrent epistaxis, coagulation disorders or other conditions that, in the opinion of the investigator, may lead to the risk of clinically significant increased bleeding
- Nasal or sinus surgery (including history of application of nasal cautery) or significant trauma to these areas
- Severe nasal airway obstruction (e.g. severe septal deviation or inferior turbinate hypertrophy) or vascularized polyp as confirmed by nasal endoscopic examination at the Screening Visit
- Have an implanted metallic or other electronic device in the head, a cardiac demand pacemaker, or an implanted defibrillator

5. Study Description
Brief Summary
This crossover design study evaluates the effectiveness of the Oculeve Intranasal Neurostimulator comparing the effect of intranasal (active) versus extranasal (control) stimulation on tear production as measured by the Jones Schirmer test in participants with dry eye disease.
Detailed Description
In this randomized, controlled study, participants will receive two applications of approximately a three-minute duration, one intranasal (active) and one extranasal (control), in randomized sequence at Visit 2 (Day 1). At Visits 3 (Day 15) and 4 (Day 29), participants will undergo two applications of approximately an eight-minute duration, one intranasal (active) and one extranasal (control), in randomized sequence. The Schirmer test is a clinically relevant and accepted measure to assess tear production over a specified time interval, generally five minutes. Tear meniscus height (TMH) and, to a lesser extent, tear meniscus area (TMA) have been reported as measures of tear quantity and/or production and have been used to diagnose dry eye disease (DED). One reliable means of measuring TMH and TMA is via use of optical coherence tomography (OCT), an established medical imaging technique that uses light to capture micrometer-resolution images from within optical scattering media such as biological tissue. Due to the non-invasive nature of the technique, this study was designed to explore the utility of TMH and TMA captured by OCT as a means of evaluating stimulated tear production following use of the study device.
