Primary Outcome Measures :
  1. Change in Fluorescein Corneal Staining (FCS) Score From Baseline to Last Observation Carried Forward (LOCF) [ Time Frame: Baseline, 4weeks ]
    FCS indicates the damage to the corneal epithelium. Per the National Eye Institute/Industry Workshop report, the cornea was divided into 5 fractions, each of which was given a staining score from 0 to 3, and the total score was calculated(0-15). 0 is better.The change from baseline (CFB) to LOCF at the end of instillation (LOCF endpoint) was used to analyze dose-response. A general linear model was used to examine if slope parameters were not equal to zero.


Secondary Outcome Measures :
  1. Change in Lissamine Green Conjunctival Staining (LGCS) Score From Baseline to Last Observation Carried Forward (LOCF) [ Time Frame: Baseline, 4weeks ]
    LGCS indicates the damage to the conjunctival epithelium. Per the National Eye Institute/Industry Workshop report, the conjunctival sac and the conjunctina was divided into 6 ractions, each of which was given a staining score from 0 to 3, and the total score was calculated(0-18). 0 is better. The CFB to each study time point was compared between the active-drug groups and the placebo group, and LOCF endpoint scores were used to compare the active-drug groups and the placebo group. In each treatment group, baseline scores and those obtained at each study time point were compared.
