The purpose of this study is to evaluate the repeated use of SYSTANE® BALANCE on stabilizing the tear film of dry eye patients with an unstable tear film.

Primary Purpose: Treatment
Official Title: Evaluation of SYSTANE® BALANCE on Conjunctival Staining (CS) Visual Performance (VP) and Tear Film Kinetics (TFK) in Dry Eye Subjects With Lipid Deficiency

Primary Outcome Measures:
  • Mean Bulbar Conjunctival Staining [ Time Frame: Month 1 ]
    The conjunctival staining present in the bulbar area was evaluated 120 minutes post eyedrop instillation using a slit lamp with digital image capture and lissamine green strips. Staining coverage as a percentage of the exposed bulbar conjunctiva is reported. A lower percentage in staining area represents a better outcome.

Secondary Outcome Measures:
  • High Contrast logMAR Time Controlled Visual Acuity (TCVA) [ Time Frame: Month 1 ]
    TCVA (functional visual performance) was measured with both eyes together under controlled lighting, contrast and temporal conditions using the OTG computerized vision testing system prior to eyedrop instillation (baseline) and at 60, 90, and 120 minutes post eyedrop instillation with the subject's up-to-date vision correction in place. TCVA is measured in logarithm of the minimum angle of resolution (logMAR), with logMAR acuity of 0.0 considered normal distance eyesight. A negative logMAR value denotes better visual acuity.

  • Non Invasive Tear Film Break-up-time (NIBUT) [ Time Frame: Month 1 ]
    NIBUT was measured prior to eyedrop instillation (baseline) and at 60, 90, and 120 minutes post eyedrop instillation. The time elapsed between eye opening after a blink and the appearance of the first dark spot within the tear film as observed with a specialized illumination source was recorded. A higher number represents a lengthening in the tear film break up time and greater perceived ocular comfort.
