Abstract

To compare the effect of intense pulsed light (IPL) therapy and conventional treatments in meibomian gland dysfunction (MGD)-related dry eye disease (DED). A literature search was conducted in PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP, and China Biology Medicine (CBM) up to January 2022. Randomized controlled trials (RCTs) were included. Mean differences (MDs) and their 95% confidence intervals (CIs) were calculated. A meta-analysis concerning changes in tear break-up time (BUT), changes in Ocular Surface Disease Index (OSDI) scores, changes in non-invasively measured tear break-up time (NIBUT), changes in corneal and conjunctival fluorescein staining (CFS) scores, and changes in Standard Patient Evaluation of Eye Dryness (SPEED) scores was carried out. The initial search identified a total of 1842 records in the databases, and 11 studies were included in the final analysis. Compared to conventional therapies, IPL therapy was associated with significantly reduced OSDI (MD, - 7.49; 95% CI, - 12.47 to - 2.5) and SPEED (MD, - 3.28; 95% CI, - 5.64 to - 0.93) scores, while BUT (MD, 1.94; 95% CI, 1.19 ~ 2.69) and NIBUT (MD, 2.55; 95% CI, 1.07 ~ 4.04) significantly increased. No significant difference was found in the change in CFS between the two groups. Both IPL treatment and traditional treatments are effective in the treatment of MGD-related DED. IPL application seems to be superior to traditional treatments.
