About

The purpose of this study is to demonstrate the superior efficacy of Systane® Balance over Preservative-Free 0.9% Saline following 35 days of QID (4 times a day) dosing in treating dry eye subjects with lipid deficiency.

Full description

This study consisted of 4 visits conducted during 3 sequential phases: the Run-in Phase (which included a screening visit and run-in period), Treatment Phase I and Treatment Phase II. In Phase I, subjects were randomized to either Systane® Balance or Saline and dosed 4 times a day for 35 days. In Phase II (Day 35-90) subjects continued to dose with their assigned product on an as-needed basis.

Enrollment: 279 patients
