Restasis® will not present instant relief, a therapeutic benefit is normally noted in 2-4 months.
Contact Lenses
Merely changing the kind of contact lens is extremely hardly ever adequate to supply enough, consistent relief. Careful collection of the contact lens material can often be helpful and is one from the lots of treatment options obtainable to us.
