Any possible health issues for a hamster missing an eye?

[gizmo]

I finally got my butt to the pet store. (I've been afraid to call or go in, plus been mega busy and figured since they never called me, that it was bad news... but turns out they lost my number). Izzie is still alive. She has lost that eye though. I now need to decide if I should take her back. Any possible health issues with missing an eye? I know she can cope without it, but I'm wondering about possible health issues. I'm assuming the problem was she somehow got it infected or something since it did swell up and got so bad so fast... I can't afford taking her to a vet too much (gonna call up and find out what the price of an actual appointment is since I think they were giving me emergency fees which were ridiculously crazy). No bashing please, I just need to know what possible issues I could face if I took her back with her missing the eye.
