The primary endpoint was meibum quality score at 16- and 24-week follow-ups; secondary endpoints were ocular surface index scores, tear film lipid layer thicknesses, tear break up times (TBUTs), Oxford scheme grades, and meibography grades at 16- and 24-week follow-ups. Adverse events, uncorrected visual acuities, best-corrected visual acuities, and intraocular pressures were also recorded.Results: Sixteen patients (four men and 12 women; mean age, 56.38 ± 8.64 years) were included. Meibum quality scores at the 16-week follow-up were significantly lower than scores at baseline (p=0.043) and at the 24-week follow-up (p=0.015). TBUT was significantly exacerbated at the 24-week follow-up, compared with baseline (p=0.001) and the 16-week follow-up (p=0.006). There were no significant changes in other parameters. All adverse events were mild and resolved without additional treatment.Conclusion: Combined application of three modes of 2940-nm Er:YAG and 1064-nm Nd:YAG lasers on upper and lower eyelids significantly improved meibum quality in patients with MGD; it ameliorated symptoms and signs of dry eye disease at 4 weeks after completion of laser treatment.Keywords: dry eye, erbium:YAG, meibomian gland dysfunction, meibum, neodymium:YAGKasetsuwan NUthaithammarat LPiyacomn YReinprayoon UChatchavalvanich CPanchaprateep RDove Medical Pressarticledry eyeerbium:yagmeibomian gland dysfunctionmeibumneodynium:yagOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 15, Pp 3065-3073 (2021)
