PURPOSE: To evaluate the efficacy of combined Intense Pulsed Light (IPL) and Low-Level Light Therapy (LLLT) in treatment of Meibomian Gland Dysfunction (MGD).

METHODS AND ANALYSIS: In this prospective study, 70 patients with refractory MGD were enrolled; group 1 received 3 consecutive sessions of IPL + LLLT treatment using Eye-light® on day 1, day 15 and day 45; group 2 received hyaluronate sodium 2 mg/ml drops 3 times a day for 6 months. Patients underwent at baseline, and after 3 and 6 months Ocular Surface Disease Index (OSDI) questionnaire, Symptom Assessment in Dry Eye (SANDE), tear-film breakup time (TBUT), fluorescein ocular surface staining, meibum expressibility and quality evaluations. Keratograph 5M (Oculus, Germany) was used to assess NIBUT, tear meniscus height (TMH), meibography, and bulbar redness score.

RESULTS: At 6 months a significant improvement of OSDI (p = 0.03), SANDE (p = 0.02), NIBUT (p = p < 0.0001), TMH (p = 0.04), TBUT (p = 0.02), corneal-conjunctival staining score (p = 0.02), lid margin score (p < 0.0001), and bulbar redness score (p = 0.001) were recorded in group 1. Comparing the two groups, statistically significant differences were observed at 6 months in TBUT (p = 0.03), lid margin score (p < 0.001), Meibum expressibility (p = 0.03) and NIBUT (p < 0.001). No adverse events were recorded throughout the follow-up period.

CONCLUSION: This study confirmed the efficacy and safety of combined IPL and LLLT demonstrating its superiority compared to topical treatment.
