Outcome Measures

Primary Outcomes (2)

  • Corneal Staining Severity

    Severity of staining was recorded for each region using a scale of 0-none to 4-patch \>/=1mm. Analysis of staining was performed by averaging the scores from the five regions for each eye, then identifying the subject's worse eye at each visit. Mean total severity was calcuated from all identified eyes for each visit.

    Baseline, 2 Hour Period, 4 Hour Period

  • Corneal Staining Area

    Analysis of staining area was performed by averaging the values from the five regions for each eye and then identifying the subject's worse eye at each visit. Mean total area was calculated from all identified eyes for each visit.

    Baseline, 2 Hour Period, 4 Hour Period

Secondary Outcomes (2)

  • Subjective Comfort

    Visit 1: Baseline; Visit 2: 2 hours, Visit 3: 4 hours

  • Subjective Dryness

    Visit 1: Baseline; Visit 2: 2 hours, Visit 3: 4 hours

  • Type 2 (macropunctate) or greater corneal staining in any region in either eye as observed by slit-lamp at Visit 1 of each study period
  • Sum of the type of corneal staining greater than or equal to 4 across entire cornea in either eye as observed by slit-lamp at Visit 1 of each study period
  • Conjunctival staining covering greater than or equal to 20% in 2 or more corneal regions in either eye as observed by slit-lamp at Visit 1 of each study period
  • Conjunctival injection greater than Grade 2 (moderate-diffuse redness) in either eye as observed by slit-lamp at Visit 1 of each study period
  • Abnormal lenticular opacity in the visual axis of the lens in either eye
  • Use of concomitant topical Rx or over-the-counter (OTC) ocular medications
  • History of seasonal allergies with significant ocular side effects which may have an adverse impact on contact lens wear
