Managing Severe Evaporative Dry Eye with Intense Pulsed Light Therapy.

Abstract

INTRODUCTION:

This study assessed the efficacy and safety of intense pulsed light (IPL) therapy in participants with severe evaporative dry eye disease (DED).

METHODS:

This randomized, controlled, single-center study included 49 adult participants (≥ 18 years) with severe evaporative DED who received either IPL therapy (n = 56 eyes) or sham therapy (n = 42 eyes) three times. The primary efficacy parameters were ocular surface disease index (OSDI) score, non-invasive tear breakup time (NITBUT), tear film lipid layer (TFLL), conjunctivocorneal staining score (CS), MG Score, meibomian gland (MG) quality, and MG expression score.

RESULTS:

The mean ages for the IPL group and the control group were 28.05 ± 3.41 years (57.1% female) and 28.14 ± 3.53 years (52.4% female), respectively. Comparison between the IPL group and the control group found significant differences in the mean OSDI score (22.16 ± 6.08 vs. 42.38 ± 6.60; P < 00.01), NITBUT (6.27 ± 0.84 vs. 3.86 ± 0.68; P < 0.001), TFLL (2.14 ± 0.44 vs. 3.45 ± 0.50; P < 0.001), MG Score (1.34 ± 0.55 vs. 1.88 ± 0.33; P < 0.001), MG quality (1.59 ± 0.07 vs. 2.67 ± 0.08), and MG expression (1.54 ± 0.57 vs. 2.45 ± 0.55) at 12 weeks follow-up; however, there was no significant difference in CS (3.32 ± 1.11 vs. 3.74 ± 1.04; P = 0.063).

CONCLUSION:

The findings suggest that IPL therapy is clinically beneficial in ameliorating the signs and symptoms of severe evaporative dry eye disease.
