Thera Tears that has disappearing preservatives?

[catlover]

I read this morning that TheraTears has an eye drop where the preservative disappears on contact with the eye. Has anyone tried this with any luck? I'm only interested b/c the bottle would be alot better for me than the individual vials (and it's in a bottle).

This is not the same product as preservative free. The preservative alters the tear formulation and does not seem as effective for many people.
