Hi Cari,
I tried some of the ointment type ones, the stuff that is kind of like vaseline (Refresh PM, Moisture Eyes, etc.), and they didnt' work too well for me. Now I use GenTeal gel for severe dry eye, and I like it alot! It still comes in a tube like the ointments, but it is more of a gel. Some people do well with the ointment, some do better with the gel though. You might have to try them both out to see what works best for you. Good luck!
