The same happened to my son in Durham a few years ago didn't even know what it was that him but he ended up with fractured skull,fractured eye socket,shattered cheekbone and fractured jaw all this happened 7 weeks before his wedding the surgeon did wonders with it though and wasn't to bad for the photos police messed about with cctv footage so didn't find who did it at the time but he was found and took care of a few weeks later, so hope your eye ok mate and time will come for that fkn prick I hope.
