(oo)
The procedure I've heard about involves removing a layer of the
cornea, freezing it in liquid nitrogen, and turning it on a lathe
so as to make it act like a lens.  Then they stitch it back on.
Cornea surgery has been procticed for a long time, so they know
how to do it, but there are risks.  For this reason, the surgery
is recommended only for persons like airline pilots who need to
be able to pass vision tests without glasses, or for people with
severe vision problems that are correctable now only with coke-bottle
lenses.  As for me, I'd rather just grope for my specs in the morning
than have my eyeballs machined.  To my knowledge, the procedure only
works for focal length problems like myopia and hyperopia, and won't
work for astigmatism, which is the bulk of my vision problem, anyway.
I'm not sure about this, though, and these things improve all the time

As an aside, has anybody out there had experience with the new contact
lenses for astigmatism?  My eye doctor has recommended against them,
but that was a couple of years ago.
