This post is about two weeks late.   However I went and saw the surgeon again.  He told me when he removed the old cornea he found it was soft and not properly formed.  So removing it appears to have been a good choice as it was unlikely to come good.  On the other hand we still don't know what happened, but apparently the cornea may have gone wrong since it was grafted on to me.  Which is a little discouraging as the same thing could happen again.

That said the eye does seem to have been less painful then last time.  It's not all good though I've been back at work two weeks tomorrow, but several days days I've had to work reduced hours or even today not at all which is very annoying - and I think it shows a slower then typical recovery.
