Primary outcomePrimary: Aqueous Tear Evaporation Rate Before and After Use of OTC Artificial Tears — 0.047; 0.049; 0.031; 0.032 (µl/cm2/min)
Summary
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.
