2 day countdown for my lasik surgery

Well I had my final pre-op appointment today. They took measurements of my eyes again and put green drops in them, shined a blue light on them, and had me look into a purple whirlpool. Not all at the same time. The first thing they did was check my vision using one of those "standard" machines at every optometrist's office (you know, the one where they keep flipping lenses on you and say "which one is clearer, #1 or #2..... #2 or #3.... etc.), then they did other measurements, and at the very end they checked my right eye's vision again based on some of those middle measurements. I hope everything will turn out OK. I am getting excited. :)
