I used plumber's epoxy (cheaper than "green stuff" by games workshop or Apoxie Sculpt, but does the same thing, minus the ability to smooth it with water and with a much shorter sculpting time) to hold eyes in. Auto-body scratch filler putty would also work. There's a couple remixes of this dragon for eyes, that include a cross-piece to hold them in place. Super glue around the edges of the eye sockets would probably also work.
