Acuvue makes four kinds of lenses, and of those four, two are 58% water, the rest have less. Acuvue and Acuvue 2 are both 42% etafilcon A. How similar is etafilcon A to ocufilcon D? I don't know, but there are the numbers for you.
I'm sorry I wasn't able to answer your question, but I hope I've narrowed it down for you.

Thanksd for the tip on water content. This site:
http://www.aclens.com/lens-materials.asp
contact lens Materials & Water Content
tells us there are only 4 catagories:
hi-lo water content
ionic vs. nonionic water
It says that Biomedics55, Acuvue and Acuvue2 are in the same
catagory- "high water content - ionic"
So my guess is I can wear Acuvue or Acuvue2 if I'm already wearing Biomedics55
Acuvues of course ARE "inversion marked" wheras Biomedics aren't, which is THE problem I'm trying to solve!
Thanks
