I thought the reason Obito didn't go blind was because he had tons of spare Sharigan in storage from the Uchiha Clan massacre, and that he would just fuse them with his own eyes. Since most of those eyes most likely didn't have MS because they were from less powerful Uchiha like children etc., Obtio never got an EMS as a result, and the fusion would restore his sight. Just what I took from it. However, Hashirama's cells probably helped too, since these repair fusions were never shown as far as I know (Just something I assumed he did, I doubt he carried them all just for Izanagi replacements, but you never know). Correct me if I'm wrong.
