“Our study shows that it is possible to significantly improve vision that has declined in aged individuals using simple brief exposures to light wavelengths that recharge the energy system that has declined in the retina cells, rather like re-charging a battery,” said lead author Glen Jeffery, an eye researcher at University College London, in a statement released by the university.

In summary, the current study revealed that PBM could increase corneal epithelial cell migration capacity in short time. The activation of Rho-GTPase pathways was involved in this process. These results may be used for future development of PBM-based therapy for acute ocular surface diseases.
