iv got bunnies with cateracts but have fostered blind buns before,iit is important to keep the scent of things the same and i found indoors was a better enviroment for blind bunnies as they had less to worry about, of course time in a run could be ok too but its difficult for some to adapt,
i would suggest something on a flat level cage wise indoors something that he doesnt need to jump any lips or edges to get into, make sure blankets are always washed in the same scented washing powder and that you rbu a little of his scent (rub blnket onto him) before giving it back to him so he knows what it is, try and keep things in the same place as they soon learn where stuff is despite numerous bumps to begin with. also you will probebly find that he will sit on your feet a lot to work out where you are and will follow you around i dont know if they listen for your footfall or smell your feet or what but i noticed blind buns tend to follow you about more prehaps for security? a freind is always useful as a guide bun too but bonding can be perilous with the wrong bunny due to stress and unknown. block any squeezey areas up so that bun doesnt get stuck you can also tempt him with lots of yummppy scented foods into areas you prefer him to be. good luck, just ensure you talk to him and approach without any suddeness as this can startle them. they soon get used to you x
