SELECTED LIGHT WAVELENGTHS AND DELIVERY DEVICES FOR THE PREVENTION AND TREATMENT OF DRY EYE SYNDROME

摘要

Provided are methods and systems for treating or preventing dry eye syndrome in a subject. The methods involve applying light of a set of photomodulating parameters to the region of the eyelid. The light of these particular photomodulating parameters will increase the production of collagen, elastin or both thereby improving the tone of the eyelid. Improved eyelid tone will increase the level of meibum secreted through the meibomian duct thereby treating or preventing dry eye syndrome. Particular apparatuses are provided that emit and locate light of the necessary photomodulating parameters tailored for delivery to the eyelid areas activating fibroblasts specifically in this area and thereby improving eyelid tone and meibomian gland function.
