Hmmm....its hard to see from your picture, but it does have the waxy look of koi pox. Does it look like candle wax dripped on his head?
Now, the crust around the eye is a different matter. The problem with viruses like koi pox, is that sometimes secondary diseases can kill the fish unless your water is 100% pristine. Can you give us a photo of the eye crust by any chance? Does it look lumpy like cauliflowers? Is it just around the eye area or is it going into the eye? Can your fish see?
I'm curious to your answers. If it was just the koi pox, I would say to just let your fish live with it, but with the eye situation it might be best to simply euthanize the fish humanely.
Let's see some more pics if possible.
