I've never had a problem like that myself, but an uncle of mine had a similar injury happen at work when a bungee cord popped loose and the steel hook dragged across his eye. He's seen a lot of specialists since it happened about twenty years ago, but so far the best they've been able to do is to restore his vision in that eye only partially. He has to wear very strong glasses, and even then everything is blurry in that eye. I hope that you find out your injury is simpler and easier to heal. Good luck to you!
