Managing Severe Evaporative Dry Eye with Intense Pulsed Light Therapy

Area of Science:

• Ophthalmology
• Medical Technology

Background:

• Severe evaporative dry eye disease (DED) presents significant challenges in ocular surface health.
• Understanding effective treatment modalities for DED is crucial for improving patient quality of life.

Purpose of the Study:

• To evaluate the efficacy and safety of intense pulsed light (IPL) therapy.
• To assess the impact of IPL on key indicators of dry eye disease severity.

Main Methods:

• A randomized, controlled, single-center study involving 49 adult participants with severe evaporative DED.
• Participants received either IPL therapy or sham therapy three times, with outcomes measured using OSDI, NITBUT, TFLL, and meibomian gland parameters.

Main Results:

• IPL therapy demonstrated statistically significant improvements in OSDI scores, non-invasive tear breakup time (NITBUT), and tear film lipid layer (TFLL) compared to sham therapy.
• Significant enhancements were also observed in meibomian gland (MG) score, quality, and expression following IPL treatment.
• No significant difference was found in conjunctivocorneal staining scores between the groups.

Conclusions:

• Intense pulsed light (IPL) therapy is clinically effective in alleviating the signs and symptoms associated with severe evaporative dry eye disease.
• IPL therapy represents a promising therapeutic option for managing severe DED.
