The IBF welterweight champion's career was almost brought to an end by the incident in September, but he is already setting his sights on Khan and the unbeaten Floyd Mayweather Jr.
"I'm thinking positive because I have to, but believe me, I will get better and then I'll smash Amir Khan," Brook told the Daily Mail. "Nothing will stop me from coming back and defending. Nothing.
"The dream scenario would then be to fight Floyd Mayweather. I'm a young lion and I believe I can be one of the greats."
Brook has not been beaten in any of his 33 professional fights.
