Arm Type
Experimental
Active Comparator
Arm Label
glycerin
polyethylene glycol 400/propylene glycol
Arm Description
One eye will randomly receive a single instillation of one drop of a new formulation of an artificial tear containing glycerin 1% as an active with polylysine-graft-polyethylene glycol as an excipient.
The other eye will receive a single instillation of one drop of an artificial tear with propylene glycol (0.3%) and polyethylene glycol (0.4%) as active ingredients with hydroxypropyl-guar as a gelling agent.
Outcomes
Primary Outcome Measures
Noninvasive Tear Film Break-up Time

5. Study Description
Brief Summary
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.
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.
