I've dealt with dry eyes for years, and it is not Sjogren's. It's Meibomian gland disfunction. I use the Systane wipes, which have some tea tree oil in them, which has been shown to kill demodex. But recently I was put on XDemvy, which is a new prescription med for demodex. It is drops you use for 6 weeks (because the life cycle of the mites is 3 weeks), and after years of suffering with the mites, they are gone! No more crusty stuff on my eyelashes every morning, and you can even see that the Meibomian glands are no longer swollen. The downside is that even after my insurance paid, the medication was very expensive. For me, with years of dealing with this, it was worth it. As a result, my dry eye symptoms are better, but not gone. So, I still use Xiidra drops, and Refresh Optive Advanced eye drops, which is what my ophthalmologist told me to use. Unfortunately, I still have symptoms. I play the cello, and I find that even with all of this care, about halfway through a rehearsal, my eyes become so dry I can't see the music. I've been told by my doctor that just like other sebaceous glands, the Meibomian glands produce less sebum every year, so I have to supplement with drops. Hopefully this helps someone.
