The Mayo Clinic Blog put up a post about a new treatment for dry eye. Intense Pulsed Light Therapy is being used, at the Mayo Clinic in Arizona, for patients who have tried other various therapies to relieve their dry eye.
The blog post describes the therapy in this way...
"IPL uses bursts of light directed at the lower eyelids and upper cheek
areas that heat the eyelid glands that are blocked with stagnant
secretions. The physician is then able to manually express the stagnant
material from the eyelids."
An interesting new therapy. There was also a video, which I've added to the bottom of this, which explains the therapy in more detail, if you are interested in viewing it.
