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

Figure 3

Tear break-up time (TBUT) and tear meniscus height (TMH). Notes: TBUT at D15 (4.2 ± 1.8 s), D45 (5.0 ± 1.9 s), and D75 (4.5 ± 2.5 s) were significantly increased compared to that at the baseline (2.2 ± 1.5 s) (). Between the visits of D15 and D45, TBUT continuously increased while reaching no statistic difference (). Between the visits of D45 and D75, no significant difference was observed (). No significant difference was found in the assessment of upper and lower TMH in all visits. Statistical analysis was performed with paired -test with the Bonferroni correction.
