There used to be an eye texture pack that came with "Dune" eyes as a bonus. I can't remember which one it was. Maybe someone else does. If not, I'll check when I get home.

Another possibility is Dolfijntjes' "Other Worlds Eyez." It's a whole set of eye textures with no whites and no pupils. Every color of the rainbow, and then some.
