Eye goop in dry eyes?

I have had problems with dry eyes and i have contacts. I use drops every once in a while when they start to get dry. However, usually when i first put my contacts in and my eyes are rewetted by doing this, a goop will form in my eyes. This leaves me with the choice to either leave it or take it out with my finger. Since I do have dry eyes, I want to know if that goop serves a purpose such as moisturizing my eyes or if it will make things worse and should be taken out. I know its generally in your eyes all the time but I just want whats best to prevent dryness.
