Contacts for astigmatism

    For astigmatism, especially if using RGP type lenses, it seems like you
    could build the backside of the lens to fairly precisely match the
    shape of the cornea. With it like this, the lens would suck in to the
    cornea in a known orientation, so rotation would not be an issue
    (assuming enough corneal astigmatism, and thin enough tear layer).
    With that, the outer surface of the lens could be built to provide the
    desired correction.

    Why is this a bad idea? I assume someone has thought of it. Is it
    just too hard to manufacture super custom lenses like that?

    My doc offers these or something similar. I will have to
    check to see what it's called. They use the raw data from
    a corneal topographer to manufacture the lenses.

    hmmm, just checked his website. It's not on there any more.
    Wonder if the company didn't make it or something? I'll
    ask next time I go in.

    Maybe they couldn't live up to their own hype. A common tale.
