  Purpose
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.

Condition Intervention
Keratoconjunctivitis Sicca Drug: glycerin Drug: polyethylene glycol 400/propylene glycol

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Randomized, Masked Exploratory Trial Comparing the Effect of Two Different Over-the-Counter Artificial Tear Preparations on Tear Film Break-up Time

Primary Outcome Measures:
  • Noninvasive Tear Film Break-up Time [ Time Frame: 15 minutes after eye drop instillation ]
    State-of-the-art methodology to assess tear stability.


Secondary Outcome Measures:
  • Fluorescein Tear Film Break-up Time [ Time Frame: 120 minutes after eye drops instillation ]
    Standard clinical assessment methodology for assessing tear stability.


Enrollment: 16

Study Completion Date: August 2008
Primary Completion Date: August 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: glycerin
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.
Drug: glycerin
Eye drop with active agent glycerin 1%, new topical ophthalmic formulation with polylysine-graft-polyethylene glycol as an excipient, single instillation.
Other Name: Eyeon Protect(TM)
Active Comparator: polyethylene glycol 400/propylene glycol
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.
Drug: polyethylene glycol 400/propylene glycol
Eye drop with the active agents polyethylene glycol 400 0.4% /propylene glycol 0.3%, topical ophthalmic formulation, single instillation
Other Name: Systane(R)

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.
