SPEED score: control group (n = 20); IPL-MGX group (n = 23). Other characteristics: control group (n = 40 eyes); IPL-MGX group (n = 46 eyes). p values were determined with the Wilcoxon signed-rank test vs. baseline or Mann–Whitney U test vs. control with Bonferroni’s correction (* adjusted p < 0.05, ** adjusted p < 0.001). SPEED, standard patient evaluation of eye dryness; LLT, lipid layer thickness; NIBUT, noninvasive breakup time; FUBT, fluorescein breakup time; Fluo, fluorescein staining; SE, standard errors; SD, standard deviations.
