| Summary: | The purpose of this study was to compare the efficacy of Intense Pulsed Light (IPL) therapy for meibomian gland dysfunction (MGD) using the new AQUA CEL (AC, Jeisys) device and the traditional M22 (Lumenis) device. A total of 59 eyes of 59 patients with MGD (12 men and 47 women, mean age 49 ± 12 years) were enrolled. They randomly received four sessions of IPL therapy every three weeks either with AC (30 eyes) or M22 (29 eyes). Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire score, noninvasive breakup time (NIBUT), lid margin abnormalities, corneal and conjunctival fluorescein staining, fluorescein breakup time (FBUT), Schirmer’s test, meiboscore and meibum grade were evaluated before treatment and one month after treatment. Before IPL, no significant differences were seen in age, gender, or measured parameters between the AC and M22 groups (<i>p</i> > 0.05, respectively). SPEED score, NIBUT, lid margin abnormalities, fluorescein staining, FBUT, and meibum grade improved significantly in both groups after IPL compared to before IPL (<i>p</i> < 0.001, respectively). There were no significant differences in measured parameters between the two groups after IPL (<i>p</i> > 0.05, respectively). IPL therapy with AC and M22 devices has been shown to be equally effective for the treatment of MGD.
