The multi-center, double-blind, randomised, placebo-controlled clinical trial evaluated 38 post-menopausal women with tear dysfunction in both eyes.

The trial was conducted at Baylor College of Medicine and Virginia Eye Consultants. Professor of Ophthalmology Stephen C. Pflugfelder said “"Within three months, the group treated with HydroEye showed statistically significant improvements in the irritation symptoms of dry eye, and no progression of ocular surface inflammation or corneal irregularity. The placebo group's dry eye symptoms actually worsened over the six-month testing period" said Pflugfelder. "HydroEye clearly had a positive impact on these patients with moderate to severe dry eye."
While there are other dry eye treatment options available, most have unpleasant side effects, provide only transient relief, or have high costs, and/or compliance issues.
