Fermin Silva Cayatopa, Lizbeth Katherine Vilela Lazo, Pedro Tinoco Mendez, Ana Luisa Gonzalez Mendez

Aim: To evaluate the safety and efficacy of low-level light therapy+meibomian gland compression in patients with evaporative dry eye due to meibomian gland dysfunction.

Materials and methods: Prospective study that included 39 patients who underwent low-level light therapy with eye light^®+meibomian gland compression at Clinica La Luz in Lima, Peru. Performing a total of 4 sessions with a time interval of 15 days per session with 15 mins duration. Evaluating the Ocular Surface Disease Index (OSDI) questionnaire, Non-invasive Keratograph Break-up Time (NIKBUT), non-invasive tear rupture time, non-invasive meniscometry, pre-meibography to see the degree of atrophy, quality and quantity of meibum compression of meibomian glands, classified from 1 to 4, the presence and decrease of telangiectasias.

Results: In NIKBUT, mean (± SD) before 3.93 ± 1.61, one month after the first 2 sessions 13.57 ± 4.31, up to 8 months of follow-up 19.36 ± 3.32. Being statistically significant (P<0.001). In meniscometry, mean (± SD) before 0.19 ± 0.02, one month after the first 2 sessions 0.30 ± 0.05, 0.32 ± 0.04 after 6 months of follow-up, being statistically significant (P<0.001). In OSDI, the mean (± SD ) pre was 38.85 ± 8.02 , at month 13.03 ± 5.77 and 3 months 13.54 ± 2.98 and 6 months the mean (± SD ) pre was 12.64 ± 3.02. Being statistically significant (P<0.001).

Conclusion: Low Level light Therapy (LLLT)+meibomian gland compression is safe and effective, reducing the symptoms and signs of dry eye for up to 8 months of follow-up. Being an alternative option for patients who do not improve with conventional treatment. However, more long-term studies are needed.
