Leo rescue, mostly confirmation on what I'm doing

[LotusCorvus]

Ok, first, the terrible cell-phone pics:





Major malnutrition and MBD, and whatever's going on with his clouded eye. Am I right so far?

When I picked him up he was on sand with no hides, no calcium dish, and a dish full of freeze-dried "leopard gecko food", and the guy who had him would feed this leo 2 superworms twice a day. Dude was trying, but... dear gods.

Gecko dude is currently in a pretty sparse cage with a quick make-shift humid hide. I've given him a small dish of phoenix worms to see if he'll eat them, and I've got crickets that I'll try feeding him in the morning once they've had a chance to eat up their gut-load goo.

Is there anything else I can do for him? I've never had a leo before, just snakes and cresties. I've been looking through the posts for similar situations, but it's taking a bit of digging. I also kind of just wanted to show him off. Despite his awful condition he's a very pretty boy, cloudy eye and all.

Thank you!
