Condition focus: Dry Eye Disease & Meibomian Gland Dysfunction (MGD)
This study evaluated photobiomodulation and intense pulsed light therapy as rescue treatment options for patients with refractory meibomian gland dysfunction who had not responded adequately to conventional management strategies. Patients who had failed standard therapies including warm compresses, lid hygiene, and topical treatments received either PBM or IPL interventions. Results demonstrated that light-based therapies provided meaningful symptom relief and objective improvements in meibomian gland function for patients with treatment-resistant MGD.
The findings support light-based modalities as effective second-line options when first-line MGD treatments prove insufficient, offering new therapeutic pathways for patients with chronic, refractory dry eye disease.
WaveFront Alignment:
While this study evaluated both PBM and IPL protocols, the demonstrated benefits in refractory MGD support the rationale for the Spectral WaveFront’s 670 nm and 810 nm wavelengths. WaveFront’s non-thermal, mitochondrial-targeted approach addresses eyelid margin metabolism and inflammatory pathways relevant to meibomian gland function and tear film stability.

Editor’s note: Solomos 2021 demonstrates that light-based therapies can benefit patients who fail conventional MGD management. For IPL outcomes in ocular rosacea and MGD, see Toyos 2015 and Shergill 2024. PBM-specific dry eye outcomes are detailed in Park 2022 and Antwi 2024. Thermal approaches to meibum lipid normalization are reviewed in Borchman 2019.
