Notes: Scores are indicated as mean ± SD.

^*P<0.0001 for significant change of hyperemia score compared with baseline by Wilcoxon signed rank test.

^†P<0.01 for significant difference of SPK score at each time point compared with other corneal area by Wilcoxon signed rank test.

Abbreviations: SD, standard deviation; SPK, superficial punctate keratopathy.
