I Had RAI 3 Times 9 Years Ago. At First

I had RAI 3 times 9 years ago. At first I had dry mouth for a couple of months. It stopped, but same week; my eyes started tearing non-stop and making pus till this day. I am seeing optometrists and nothing has worked thus far. I've been prescribed steroids eye drops, Systane gel, and Restasis. I even try hot compress 3 to 5 times a day, but to no avail. What are my options? My life has been put on hold for the last 9 years. And vision is blurry now.
