This treatment has exceptional results specifically for treatment of dry eye caused by Meibomian Gland Dysfunction (MGD). If MGD is causing your dry eye, it is worth the $. The treatment is minimally invasive meaning no need for punctal plugs, lid scrubs and other very painful alternatives. I have been treated and can now wear contacts to correct my vision which before didn't even cross my mind because I had so much trouble with my eyes!
I am not familiar with the product. Sounds too good to be try. It may help, but I believe you need frequent treatment.
