bubbagazoo - look into waveguide lasik. that's what i had done. my #1 concern was spherical abberrations causing night vision issues. i learned something VERY interesting, and that was that i had artifacts in my night vision with contacts and with glasses! imagine my surprise! i had both starbursts and halos PRIOR to the surgery.
i had the surgery, and the artifacts have lessened considerably. my night vision rocks now, and it's one of the things that makes me happy that i had it done. it's a little different for everyone, but the waveguide has such a small ablation area that they can really clean up a lot of the defects you might currently have.
