A new step forward in understanding ocular surface recovery: new results from a double-masked, RCT reveal how LM™ LLLT (PBM) modulates tear biomarkers involved in tissue repair, neurotrophic support, and inflammation regulation after cataract surgery.
Key outcomes:
✅ Significant increase in GDF-15 in the LLLT group, suggesting activation of intrinsic anti-inflammatory pathways
✅ Increase in PDGF-CC in the LLLT group, supporting reparative pathways involved in tissue reconstruction and epithelial restoration
✅ More pronounced β-NGF increase in LLLT-treated patients, associated with nerve regeneration, epithelial recovery, and tear film stability
✅ Higher clinical improvement rate in the LLLT group vs sham-treated patients: 44.2% vs 4.4%
Together, these results support LM™ LLLT (PBM) as a practical perioperative strategy associated with faster ocular surface recovery, symptom reduction, and tear film stabilization.
Congratulations to the authors — Dr. Timofte Madalina, Dr. Daniel Constantin Branisteanu & team — for their valuable contribution to advancing ocular surface research.
