Abstract
Purpose
To evaluate the clinical efficacy and safety of combination treatment with intense pulsed light (IPL), LipiFlow thermal pulsation, and manual meibomian gland expression (MGX) for patients with refractory meibomian gland dysfunction (MGD).
Methods
A total of 23 eyes from 23 patients who underwent combination treatment with IPL, LipiFlow, and MGX for refractory MGD were included in the study. All patients were followed up for 12 months after the first treatment. All patients were examined prior to treatment and underwent three sessions of IPL, LipiFlow, and MGX, a subsequent three sessions of IPL and MGX, and six subsequent sessions of MGX. Patients were examined 10 weeks, 6 months, and 12 months after the first treatment. The ophthalmologic examination included ocular surface disease index (OSDI), non-invasive tearfilm break-up time (NIBUT), lipid layer thickness (LLT), meibomian gland expressibility (MGE), meibomian gland morphology (meiboscore), and tear meniscus height (TMH).
Results
OSDI, NIBUT, LLT, and MGE significantly improved with treatment, which was maintained during the follow-up period. TMH and meiboscore remained unchanged throughout follow-up. No serious adverse events occurred during follow-up.
Conclusions
Combination therapy with IPL, LipiFlow, and MGX was clinically effective and safe for the treatment of refractory MGD. Combination treatment could be considered for patients with insufficient improvement despite conventional MGD treatments, including IPL treatment with MGX.
