@TheKillman, Madara isn't maintaining Izanagi at all. Izanagi was only set to activate if and when Madara died. It's not like Izanagi was always active while Madara was doing whatever. He sealed it in his eye to activate when certain requirements were set. In this case, his certain requirements were his death + a few days or so.

Just like when Itachi sealed Amaterasu in Sasuke's eye, it didn't activate until the requirements were met.

Madara didn't maintain anything, all he did was seal a jutsu in his eye. The jutsu activated only after he died. So he only lost his eye once he died.
