Evaluate the efficacy and safety of LipiFlow® thermal pulsation treatment system compared with lid massage combined warm compress in Chinese patients with meibomian gland dysfunction (MGD). Patients (n = 100 eyes, 50 subjects) diagnosed with MGD were recruited for this prospective, randomized, 3-month clinical trial. In Lipiflow group, patients (n = 50 eyes) received a single LipiFlow® thermal pulsation system treatment. In warm compress group, patients (n = 50 eyes) underwent warm compress daily for two weeks after an initial manual lid massage. Patients' symptoms were evaluated using Standard Patient Evaluation for Eye Dryness (SPEED) questionnaire. Safety parameters included best-corrected visual acuity (BCVA), intraocular pressure (IOP) and objective parameters including meibomian glands yielding lipid secretion (MGYLS) number, meibomian glands secretion (MGS) score, lipid layer thickness (LLT), tear-film breakup time (TBUT), corneal fluorescein staining (CFS) were measured and presented from baseline and to 3 months post-treatment. Baseline parameters in both groups were comparable (p > 0.05). SPEED score and TBUT improved in two groups from baseline to 3 months. MGYLS number, MGS score, LLT improved in LipiFlow group and these improvements were maintained with no significant regression at 3 months. CFS showed significant improvement in warm compress group at 1 month compared with LipiFlow group. Moreover, the correlation analysis indicated LLT was positively correlated with TBUT, MGS score, and MGYLS number. A single 12-min LipiFlow treatment is an effective therapy for MGD patients and can achieve improvements in symptoms alleviation and meibomian gland lipid secretion function lasting for at least 3 months. © 2022.
