A few years ago I had a scratch on one eye that resulted in a large tear to my cornea. It was absolutely agonising but the doctor I saw at A&E assured me that it would heal quickly by itself, and so it did.
There was fortunately no damage to my vision, however I sporadically get bouts of intense pain in that eye, usually if I try to open my eye(s) quickly when I've just woken up. I had an attack in the middle of the night last night and it was horrible - wave upon wave of pain, and nothing I can do - I just have to lie there and wait for it to stop.
I really need to see someone about this, but I'm not sure who. I saw an optician about a year after the scratch, just to check things out and was told it looked fine (actually the optician was awful - he seemed totally disinterested and disengaged, but I guess I was just unlucky).
So what do you think - try another optician or go see my GP?
