Corneal staining score at 4 and 12 weeks in each per-protocol set group. Corneal staining scores of 0.05% CsA + 0.5% CMC and 0.15% HA + 0.05% CsA show significant difference on 4 weeks. (P < 0.05 by analysis of covariance). On 12 weeks all groups showed no significant intergroup difference (Mean value ± standard deviation, P > 0.05 by analysis of covariance).
