Photobiomodulation (PBM) has become an increasingly important component of modern Interventional Dry Eye strategies, particularly in patients with meibomian gland dysfunction (MGD) and chronic evaporative dry eye.
How photobiomodulation works
By delivering visible red and near-infrared light, PBM induces photochemical changes within mitochondria, enhances cellular energy production, modulates inflammatory pathways, and supports tissue repair.
Its non-invasive profile, excellent tolerability, and compatibility with other device-based treatments make it especially valuable in multimodal therapeutic protocols.
Applied to the ocular surface and periocular tissues, PBM may improve meibomian gland function, promote tear film stability, reduce lid margin inflammation, and enhance ocular comfort.
WIDES Approach
Within the WIDES approach, photobiomodulation is not viewed as an isolated technology, but as part of a broader synergistic strategy combining lubricants, lid hygiene, IPL, electrical current devices, thermotherapies, and radiofrequency, according to each patient's phenotype. In this context, PBM represents a scientifically grounded and clinically relevant tool for restoring ocular surface homeostasis in complex dry eye disease.
