Hi Pat,
I hope you get some quick relief from the rx's he gave you. Thank you for asking those questions for us...((Hugs)). My Opthamologist gives me two different eye drops. One of them is Systene and I can't remember the name of the other. Sometimes I have to use them several times a day for the sandpaper feeling. I also have an rx for Gentamicin eye drops when they get infected that helps alot. I agree, staying on top of this helps.
Take care and let us know how the rx's work for you. You are in my thoughts and prayers.
Babs
