My wife is going in for her second eye cornea replacement. She is enjoying being able to see clearly out of one eye and looking forward to the other eye being done. Is cornea replacement not an option for your eyes? I've know a few people that had the Lasik surgery one was real happy but one was not since his eye sight returned to what it was before the surgery after about a year.

I honestly do not think it makes a difference on what you tell your healthcare provider about using your information, they are going to do it anyway and there is no method available to find out if they are selling or giving your information away.
