Brief summary

The purpose of this study was to evaluate the ability of SYSTANE® BALANCE dosed 4 times a day for 30 days to increase non-invasive tear film break up time over baseline, compared to a saline control, in dry eye subjects with lipid deficiency.

Inclusion criteria

* Read, sign, and date an information consent; * Willing and able to follow instructions and maintain the appointment schedule; * Best-corrected visual acuity of 0.6 logMAR or better in each eye as assessed at Visit 1; * Must not have used any topical ocular drops for approximately 24 hours prior to Visit 1; * Meet protocol-specified criteria for dry eye at Visit 1; * Other protocol-defined inclusion criteria may apply.

Exclusion criteria

* History or evidence of ocular or intraocular surgery or serious ocular trauma in either eye within the past six months; * Current punctal occlusion of any type (e.g., collagen plugs, silicon plugs); * History of intolerance or hypersensitivity to any component of the study medications; * History or evidence of epithelial herpes simplex keratitis (dendritic keratitis); vaccinia; active or recent varicella viral disease of the cornea and/or conjunctiva; chronic bacterial disease of the cornea and/or conjunctiva and/or eyelids; mycobacterial infection of the eye; and/or fungal disease of the eye; * Use of any concomitant topical ocular medications during the study period; * Use of systemic medications that may contribute to dry eye unless on a stable dosing regimen for a minimum of 30 days prior to Visit 1; * Ocular conditions such as conjunctival infections, iritis, or any other ocular condition that may preclude the safe administration of either drop under investigation; * Unwilling to discontinue contact lens wear during the study period. Contact lens wear must have been discontinued at least one week prior to Visit 1. * Participation in an investigational drug or device study within 30 days of entering this study; * Other protocol-defined

Design outcomes

MeasureTime frameDescription
Mean Change From Baseline in NITFBUT at Day 30Baseline (Day 0), Day 30NITFBUT is defined as the time elapsed between eye opening after a blink and the appearance of the first break in the tear film, ie, dry area. NITFBUT was evaluated noninvasively with a Tearscope. One eye from each participant was chosen as the study eye, and only data for the study eye contributed to the analysis. A positive change value indicates an improvement in tear film stability, which may improve dry eye symptoms in dry eye sufferers.
