I doubt Oda goes Mangekyo Sharingan on Zoro. He has a visible scar crossing his eye, proof of the (probably) brutal training he had to endure during the past 2 years. And to be honest, Mihawk is crazy enough to do something like that.

It was probably like this: Mihawk: "Lets see if fate saves your stereoscopic vision from my Black Sword"

-Slash-

Mihawk: "........."
