Brief Summary

Laser corneal refractive surgery is a widely adopted approach for correcting refractive errors, but postoperative dry eye remains a common side effect. Intense Pulsed Light (IPL) and Low-Level Light Therapy (LLLT) are two emerging treatments that have shown potential in managing dry eye disease. However, their role as a prophylactic treatment in patients without pre-existing symptomatic dry eye undergoing refractive surgery has not been explored.

Outcome Measures

Primary Outcomes (1)

  • French version of Ocular Surface Disease Index (OSDI) score

    The OSDI questionnaire measures frequency of symptoms, environmental triggers and vision related quality of life. OSDI values range from 0 to 100. A score between 13 and 22 excluded indicates a medium intensity eye dryness. A score between 22 and 33 indicated a moderate intensity eye dryness. A score above 33 indicates a severe eye dryness.

    1 month post-operative

Secondary Outcomes (6)

  • Evolution of Fluorescein Break-up Time (FBUT) over the 6 first months post-operative

    6 months post-operative

  • Evolution of Schirmer I test over the 6 first months post-operative

    6 months post-operative

  • Evolution of Meibomian Gland Dropout over the 6 first months post-operative

    6 months post-operative

  • Evolution of the Oxford score over the 6 first months post-operative
