Actual eyes don't seem to be a part of the soul, just a physical part of the body. Otherwise, both Itachi and Nagato would be missing their eyes in the Edo Tensei version because these eyes were later taken by someone else (i.e. Sasuke and Obito respectivelly), and while Nagato's eyes weren't his own, at least that's not the case with Itachi.
