Primary Outcome Measures :
  1. Limbal Hyperemia (Redness) [ Time Frame: 2 weeks ]
    Subject distribution according to limbal hyperemia scale in each eye during the 2-week Follow-up Visit. For this scale, 0 is lowest and 4 is greatest. If present in at least one eye, then it is counted.

  2. Limbal Hyperemia (Redness) [ Time Frame: 4 weeks ]
    Subject distribution according to limbal hyperemia scale in each eye during the 4-week Follow-up Visit. For this scale, 0 is lowest and 4 is greatest. If present in at least one eye, then it is counted.

  3. Bulbar Hyperemia (Redness) [ Time Frame: 2 weeks ]
    Subject distribution according to bulbar hyperemia scale in each eye during the 2-week Follow-up Visit. For this scale, 0 is lowest and 4 is greatest. If present in at least one eye, then it is counted.

  4. Bulbar Hyperemia (Redness) [ Time Frame: 4 weeks ]
    Subject distribution according to bulbar hyperemia scale in each eye during the 4-week Follow-up Visit. For this scale, 0 is lowest and 4 is greatest. If present in at least one eye, then it is counted.

  5. Corneal Staining [ Time Frame: 2 weeks ]
    Subject distribution according to corneal staining with fluorescein scale in each eye during the 2-week Follow-up Visit. For this scale, 0 is lowest and 4 is greatest. If present in at least one eye, then it is counted.

  6. Corneal Staining [ Time Frame: 4 weeks ]
    Subject distribution according to corneal staining with fluorescein scale in each eye during the 4-week Follow-up Visit. For this scale, 0 is lowest and 4 is greatest. If present in at least one eye, then it is counted.
