The goal of this research is to evaluate and compare the effectiveness of Systane® versus Optive™ and Soothe™ 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.

Primary Outcome Measures:
  • To evaluate tear film stability after the use of OTC ATwhen using an Evaporometer in patients with a diagnosis of Keratoconjunctivitis Sicca (KCS). [ Time Frame: 4 months ]

Enrollment: 20
Study Start Date: November 2007
Study Completion Date: March 2009
Primary Completion Date: March 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1 Optive Drug: Optive
Instillation of Optive followed by Evaporametry assessment at 30 and 60 minutes
Active Comparator: 2 Systane Drug: Systane
Instillation of Systane followed by Evaporametry assessment at 30 and 60 minutes
Drug: Systane

Detailed Description:

Twenty (20) patients will be enrolled in this three -period crossover, randomized study design. During the course of the study, each patient will be treated with each test articles in the clinic at separate visits. Following the informed consent procedure, a general ocular evaluation, including corneal and conjunctival staining, Schirmer testing, 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 three treatment groups. After 1 hour, in order to eliminate any residual sodium fluorescein, patients will be administered one drop of Systane® (40 µl), Optive™ (40 µl), or and Soothe™ (40 µl) in each eye per randomization assignment. At 30 and 60 minutes following instillation of drop, evaporometry measurement will be repeated again. These tests (pre and post instillation of drops) will be performed in order to establish a comparison for later analysis. The estimated time in completing these visits will be 180 minutes per visit. Patients will be asked to return to the clinic after 2 - 14 days for evaluation of the 2nd and 3rd assigned treatment.

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 prior to one hour of their office visits.
