Evaluation of the Safety and Effectiveness of Intense Pulsed Light in the Treatment of Meibomian Gland Dysfunction

Figure 2

Meibomian gland secretion quality and expressibility. Notes: the axis represents the level or grade of the meibomian gland secretion quality and expressibility, with higher grades meaning worse quality and expressibility. Compared to the baseline, the meibomian gland secretion quality and expressibility significantly improved at the visits of D15, D45, and D75 (). Between the visits of D15 and D45, the meibomian gland secretion quality and expressibility continuously improved (). Between the visits of D45 and D75, no significant difference was observed for the secretion quality () and expressibility (). Statistical analysis was performed with paired -test with the Bonferroni correction.
