Brief Summary:
In this study, the safety and effectiveness of the Oculeve Intranasal Lacrimal Neurostimulator after 180 days of use in participants with aqueous tear deficiency will be evaluated.

Condition or disease Intervention/treatment Phase
Dry Eye Syndromes Keratoconjunctivitis Sicca Device: Intranasal Lacrimal Neurostimulator (Oculeve) Not Applicable

Detailed Description:
This is a prospective, single-arm, multicenter, open-label clinical trial in which participants will use the Oculeve Intranasal Lacrimal Neurostimulator to stimulate tear production for 180 days. Participants will have a Screening Visit within 60 days prior to the initial device application. Device application will be initiated at Day 0, at which time participants will receive training on the proper use of the device. Participants will receive follow-up visits at Days 7, 30, 90 and 180.

Device: Intranasal Lacrimal Neurostimulator (Oculeve)
Neurostimulation device

Primary Outcome Measures :
  1. Stimulated Acute Tear Production [ Time Frame: The stimulated and prestimulation (basal) measures were both performed at Day 180. ]
    Stimulated acute tear production in the study eye at Day 180 as measured by the difference between the Schirmer test score during stimulation and the test score before stimulation (basal). The Schirmer strip is placed just under the eyelid and wicks up the tears. It measures tear production on a linear scale of 0-35 mm.

Secondary Outcome Measures :
  1. Corrected Distance Visual Acuity [ Time Frame: Baseline and 6 months ]
    Change from baseline (Day 0) in corrected distance visual acuity at Day 180. Corrected visual acuity was obtained using the subject's own glasses (for subjects that wear glasses) and measured in logMAR (log of the Minimum Angle of Resolution) units using an appropriate eye chart. A logMAR score of 0.0 is equivalent to a visual acuity of 20/20 and larger logMAR values indicate a poorer visual acuity (eg. A value of 0.3 corresponds to a visual acuity of 20/40).

  2. Slit Lamp Biomicroscopy [ Time Frame: 6 months ]
    Number of subjects with clinically significant (CS) findings noted from the slit lamp biomicroscopy examinations. A slit lamp biomicroscopy examination of the eyelids, cornea, conjunctiva, anterior chamber, and lens was performed at each visit for each eye. The results were graded as normal, abnormal not clinically significant (NCS), or abnormal CS. In addition, the cornea was scored specifically for corneal edema using a 4-point scale (0=None, +1=Mild, +2=Moderate and +3=Severe). An increase in corneal edema grade of two or more was considered clinically significant and evaluated as a potential AE by the investigator.

Other Outcome Measures:
  1. Device-related Adverse Events [ Time Frame: 6 months ]
    Number of subjects who experienced any device-related adverse events.
