is it an eye dr. that you have been seeing for this? There are many kinds of eye drops be sure and use one that is perservative free. I had a cornea transplant 3 years ago and have problems with dry eyes. I find that I have a crust like stuff in the corner of my eye that I had the transplant done on but I use alot of drops during the day. their are eye doctors out there who specialize in dry eyes and it might be worth the time to try and find one in your area
