Izanagi takes your eye after the effect has passed.

So, it's my opinion that it's impossible to restore your eye with it, since your eye will only lose sight after the ability has been used up.

Now going off that, I think it's possible to use Izanagi, lose your eyesight, then use Izanagi from your other eye to bring back the first eye. So you could do THAT forever, I think... Lol
