I looked it up since it sounds like what they would call what I have. It is. My eyes haven't focused together since I was 15. I have had a prism in one lens of my glasses since then. I can't see it and no body else can see it either. I don't know about any of the other "treatments" and I sure wouldn't let them do surgery for it. The prism makes your lenses a little more expensive but it works.
