The baseline corneal staining score was not significantly different between the two groups (p = 0.518). Corneal staining scores improved at 12 weeks from baseline in both groups (AS group, from 3.09 ± 0.995 to 2.13 ± 1.185; p = 0.000 vs. PRP group, from 3.25 ± 0.844 to 2.23 ± 0.992; p = 0.000) (Table Change in dry eye parameters after 4 and 12 weeks of treatment.△ = Post treatment−Baseline.SD, standard deviation; OSDI, ocular surface disease index.*Indicates statistical significance.Ocular staining scores of the two groups. ** p < 0.01; error bars indicate standard deviation.
