1. If you want to research laser eye surgery, make sure you check out more than just cost. Make sure the surgery is all-inclusive, and includes all your optometry exams, check-ups before and after the surgery, eyedrops and other materials afterwards etc..
2. For the surgeon, give a call to your provincial College of Physicians and Surgeons and ask them if the particular doctor is a member in good standing. Ask if they have had any history of malpractice, or anything of note on their file. Also, call the Better Business Bureau to inquire about the specific clinic offering the service. Ask if they're a member, and if there have been any complaints lodged, lawsuits filed etc..
3. Go to more than one surgeon. If one surgeon tells you that you aren't a good candidate for laser eye surgery, go with their advice. They're obviously not trying to make money off you, and a good surgeon would rather turn you away than risk doing damage to your vision. When you speak to them, ask them EVERY question that comes to mind, no matter how stupid or trivial you may think it is. Here: http://www.usaeyes.org/faq/tough_questions.htm is a good list of questions to ask your surgeon.
