    Where would one source "top-notch poly", specifically what manufacturer makes it? What makes it objectively "better" than trivex? Again specifics would be great.

    Presumably the patient has always has this antimetropia and adding prism thinning isn't going to change that. It will simply move the image slightly up.

    If all you are using it for is to measure curves the material doesn't matter. If you are using it to calculate power, then you will need to calculate for the index.
