[Petite]

I would give him a few days to settle back down by himself. Talk to him, but don't try to interact physically with him just now. When you do start to interact physically, take it very slowly, at his speed rather than yours. Hamsters don't appear to have long memories, so he will forget this incident quite quickly. However, please do watch his eye; he may be in pain with it and need it checking over by a vet.
