I had a stem cell transplant 5 years ago. I have chronic lymphocitic leukemia. I have been suffering for the last year with extremely dry eyes which is caused by graft vs host disease. I have tried every eye drop available. Have also tried restasis (makes my eyes burn). I have plugs in bottom tear ducts, (helped for a short while), also had my top ducts cauterised (very painful) but worked for about 2 weeks. I also use blood syrum drops. Nothing is really working and was wondering if there is anyone out there that could give me any more suggestions?
