Tear Film Break-up Time After Instillation of Artificial Tears

October 24, 2012 updated by: Calm Water Therapeutics LLC

A Randomized, Masked Exploratory Trial Comparing the Effect of Two Different Over-the-Counter Artificial Tear Preparations on Tear Film Break-up Time

This study is an exploratory trial evaluating the tear film break-up time after a single eye drop instillation of over-the-counter artificial tears. The primary hypothesis is that tear film break up time will be greater for test than control eye.

Study Overview

Detailed Description

Subjects with varying degrees of dry eye syndrome were enrolled in a randomized, controlled, double masked, single site study. A new formulation of an artificial tear containing glycerin 1% as an active with polylysine-graft-polyethylene glycol as an excipient was compared against a leading commercial product with propylene glycol (0.3%) and polyethylene glycol (0.4%) as active ingredients with hydroxypropyl-guar as a gelling agent. The primary outcome was a comparison of tear film stability after eye drop instillation.
