Ames ... thank you. Now I have to live with only giving your time
$2.50. There should be a way, once a question is answered, to increase
the value. Writing the question may be worth $2.50 ... getting an
answer so quickly is worth so much more.

Somewhat helpful, though not the precise thing I was looking for (I
wanted something very disposable, which I should have said more
specifically in my request--although I expected the researcher would
look up "banquet roll" to see what I was talking about).  What this
researcher found is a good backup if I don't find what I'm looking
for.

Although I appreciate your description of your own experience with
trabeculectomy, I was looking for more in-depth research about the
risks of the procedure and its success rate... not simply a link to a
webMD encyclopedia entry.  Also I was interested in learning about the
reputation of the doctors and clinics that perform the procedure in
upstate NY, not simply a physician finder service.  Thanks anyway for
your efforts.
