Hi there,
You may not be aware but your question has landed in the MS community which is probably not the right community to answer this question...
All i can tell you is Restasis is typically used to treat dry eye to increase tear production, and it also helps decrease ocular surface disease, lessen the severity of dry eye symptoms and significant reduction in ocular pain postoperative with Glaucoma but i'm unaware of Restasis being used to treat Glaucoma specifically.
Below will provide you with all the different types of Glaucoma treatment options available.
