Both used their ocular powers with moderation, unlike Sasuke who got blind very quickly due to overusing Amaterasu and Susanoo during the day of the Kage Summit.

-Close genetics i.e. Izuna and Madara, Sasuke and Itachi

- the other Uchiha whose eyes you will transplant into your sockets must have Mangekyo Sharingan as well. They're the conditions we know of. I'd add a third one: having Indra's chakra. Madara and Sasuke were the only ones who could undergo the trasplant succesfully, which is rather weird.
