keratoconjunctivitis sicca
"My husband is 42 years old and has perfect (20/20) vision. He began experiencing eye trouble about two years ago. It began with a few floaters. He says he still has these floaters as well as a feeling as if there are 'shadows' being cast over his eyes/eyelids. He also complains that they burn and have a 'sand' or 'grit' feeling in them. He has been to several eye doctors, all of which have either written him off completely, or diagnosed him with having severe dry eye. He tried Restasis and they have since become worse. No relief at all. He uses the non-preservative eye drops throughout the day and others occasionally. I see quite a few people have said the same thing, the Restasis just doesn't work. The discomfort has worsened."
