Background: Dry eye syndrome, often caused by Meibomian gland dysfunction, frequently requires anti-inflammatory therapy. Intense Pulsed Light (IPL) therapy has demonstrated efficacy in various conditions by suppressing inflammation. Objective: This study aimed to evaluate IPL's effectiveness in treating dry eye syndrome at the National Ophthalmology Unit. Methods: A retrospective observational study included adult patients diagnosed with evaporative dry eye from March 2023 to March 2024. Patients underwent Keratograph® tear analysis before and after 4 IPL sessions, with pre-IPL and post-session Ocular Surface Disease Index (OSDI) assessments. Results: Fifty eyes of 25 patients showed significant improvement in OSDI scores (26.2 before IPL, 15.2 after; p < 0.05). Non-Invasive Tear Break-Up Time (NIBUT) and Jenvis score improved in the right eye, though remaining stable in the left eye. No significant changes in tear meniscus height or Meibomian gland dysfunction were observed. No procedure-related complications occurred. Conclusion: IPL therapy effectively reduced dry eye severity after 4 sessions, with significant improvements in tear film analysis, indicating its potential as a therapeutic option. Prospective and comparative studies are necessary to assess long-term safety and efficacy.
