Sorry to hear that Spidermonkey!
A friend of mine just recently had 2 seperate operations on his eyes because of a problem with his diabetes. He couldn't see for 2 months, and everything was "wavy" according to him. He hasn't worked since, and his eyesight will never go back to how it was - and might even fail altogether. He's got one kid, and another on the way. Luckily, he is a professional audio scorer, so even if he did lose his eyesight, he would still be able to work - albeit not as well and would need help from his partner. If I were to lose my eyesight, I have no idea what I would do. I would have to look for another line of work because I am an artist and that's all I know. And no skiing, and no video games!
Best of luck to you!
