Tear Film Break-up Time After Instillation of Artificial Tears
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.
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.

Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Keratoconjunctivitis Sicca
  • 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)
  • 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)
  • 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.
    Intervention: Drug: glycerin
  • 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.
    Intervention: Drug: polyethylene glycol 400/propylene glycol
