Lasik eye surgery is a terrible example for you to pick for this. Lasik is notorious for being a market where laser clinics bought the machines when Lasik was a fad and were hoping demand would stay high, and are now having to resort to unscrupulous sales tactics to recoup their losses. Laser clinics give sales commission to their eye counselors as an incentive to get you to purchase Lasik even when you might not need it or it may not be best for you [1]. They have incentives to use deceptive marketing techniques to make you think that you need it and that it is affordable, even though the price you hear on the radio is almost
never the actual price you will pay (they will tell you that the advertised price is only for
some eyes, and that yours are more complicated and require more money). They will try to convince you that there are no side effects, despite an FDA study showing that 46% of people reported visual issues
caused by Lasik, with 30% of all recipients stating that Lasik caused them to have chronic dry eye [2]. This is so commonplace that the FDA and FTC had to get involved to guide consumers about how to avoid these shady clinics and to tell these Lasik marketers to knock it off [3], [4].
I don't know about you, but I certainly don't think the 'marketplace' for procedures such as childbirths, biopsies, transplants, bone replacements, etc should look anything like the marketplace for Lasik does.
