Abstract
An antimicrobial treatment system comprises a wearable photoactivation device. The wearable photoactivation device includes a body configured to be positioned on a head of a subject over one or more eyes of the subject. The body includes one or more windows or openings that allow the one or more eyes to see through the body. The body includes one or more photoactivating light sources coupled to the body and configured to direct photoactivating light to the one or more eyes according to illumination parameters. The illumination parameters determine a dose of the photoactivating light that activates, according to photochemical kinetic reactions, a photosensitizer applied to the one or more eyes and generates reactive oxygen species that provide an antimicrobial effect in the one or more eyes, without substantially inducing cross-linking activity that produces biomechanical changes in the one or more eyes.
