I must say, what you call scribbles rather blows me away, but I suppose life is relative in most arenas. Your drawings are so spot on and amazing.

As for eye-wear, I just need reading glasses, and have been lucky in this department to date (knock on one HUGE tree or other wooden surface).
I can relate though, the idea sounds great to have the surgery, but the details can be scary. I have a couple of friends that are older, and they had it, and it worked great for them. But as you say, a tough choice.
