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

- Access Criteria
- Data access requests will be reviewed by the internal committee of Brest University Hospital (CHU de Brest). Requests must include a research proposal and analysis plan (and ethics approval/exemption if applicable). Approved requestors will be required to sign and comply with a data access/data use agreement (no re-identification; secure storage; no onward sharing; acknowledgement/citation of TEBeLiD investigators). Data will be provided via secure transfer or controlled-access environment.
De-identified (coded/pseudonymised) individual participant data from the TEBeLiD randomized trial that underlie the primary and secondary publications/final study report. Dataset includes baseline demographics/clinical characteristics, randomization group, procedural variables, follow-up outcomes (e.g., F-OSDI/OSDI, tear film break-up time, corneal staining/Oxford score, Schirmer test, meibomian gland assessment/meibography), adverse events, and protocol deviations. A data dictionary and variable coding will be provided.
