About this study
Official title: Effects of Systane® Versus Optive™ Lubricating Eye Drops in Maintaining Tear Film Stability at Determined Time Points
The goal of this research is to evaluate and compare the effectiveness of Systane® versus Optive™ on aqueous tear film stability in patients with a diagnosis of Dry Eye Syndrome and to determine the possible application for this product in the future. Systane® is marketed as over-the-counter tear lubricating therapy in the United States under the FDA monograph.
Read the detailed description
Twenty (20) patients will be enrolled in this two-period crossover, randomized study design. During the course of the study, each patient will be treated with each test article in the clinic at separate visits. Following the informed consent procedure, a general ocular evaluation, including corneal and conjunctival staining and Schirmer testing, will be done and evaporometry assessments will be completed to determine baseline tear evaporation rate. This will occur before any test article is administered to the patient.
Qualified patients will be randomized into two treatment groups. After 1 hour, in order to eliminate any residual sodium fluorescein, patients will be administered one drop of Systane® (40 µl) or Optive™ (40 µl) in each eye per randomization assignment. At 30 minutes following instillation of the drop, the evaporometry measurement will be repeated. These evaporometry tests (pre and post instillation of drops) will be performed in order to establish a comparison for later analysis. The estimated time in completing each study visit will be 180 minutes per visit. Patients will be asked to return to the clinic after 2 - 14 days for evaluation of the 2nd assigned crossover treatment (i.e. patients who initially received Optive will receive Systane and patients who initially received Systane will receive Optane).
During the interim study periods, patients will be asked to continue their pre-study routine; using their pre-study ocular lubricant or other tear products at the same frequency. Any changes in the frequency of product use during the interim period or any changes in other concomitant medications will be carefully recorded. This is especially important since many prescription products (e.g., Claritan) have significant effects on lacrimal gland physiology.
An effort will be made to schedule all study visits at approximately the same time of day in order to reduce diurnal variability. For the similar reasons, all patients will be asked not to use any lubricants or ocular medications for at least one hour prior to their office visits.

What is being measured
The primary outcome is the main question the study is designed to answer.
Aqueous Tear Evaporation Rate Before and After Use of OTC Artificial Tears
To evaluate the effect of OTC artificial tears on tear film stability, the evaporation rate (µl/cm2/min) will be determined with an Evaporometer for the left eye only of each patient. For each arm, the evaporation rates will be determined at baseline and at 30 minutes after installation of artificial tears. Evaporation rates in all cases will be determined under two different relative humidity (RH) conditions, RH from 25-35% and RH from 35-45%.
Measured: Baseline and 30 minutes after artificial tear instillation

Yes. Results are posted in the registry (first posted 19 Nov 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Aqueous Tear Evaporation Rate Before and After Use of OTC Artificial Tears (time frame: Baseline and 30 minutes after artificial tear instillation). It is what the study was designed to measure, not a finding.
