Kakashi and Obito share a blood group. It's interesting that for all the weird stuff, he did pay attention to whether the blood groups of the various transplantees were feasible. Obito, Kakashi and Madara are all O type (hence Kakashi was compatible with Obito's sharingan, and so was Madara) while Itachi and Sasuke both had AB (so again, compatible). It's so random that among all the weird science, he did pay attention to that.

Madara, by the way, used healing ninjutsu when he put in the eye. So it's likely that he simply used a very fine chakra scalpel plus medical ninjutsu to cut out the eye precisely and heal it back with ease. It's hardly the most insane thing he's done.

Huh..never noticed the blood type thing so that is interesting. As to your second comment about Madara..well yeah..he's freaking Madara, honestly one of the more powerful ninja in the series before he got Six Path Sage powers..I mean he used his Susano'o to perform hand seals and pull two meteors down from space and crash one into the other to try and smash the allied ninja. And we've seen what kinda crazy crap medical ninjutsu can do in the hands of someone like Kabuto who basically pulled a Yugioh DNA Transplant on himself using Orochimaru's DNA as well as pretty much all 5 of the Sound guardians..Madara putting in and healing an eye is child's play.
