Essentially, the surgical residents in this line don't have enough patients
to practice on, so, they are willing to do it for free. You see, knee
surgeons might have patients waiting in long lines, but there isn't a big
supply of LASIK patients. Truth is people wearing glasses tend to do better,
and would rather pay extra thousands of bucks for a veteran.
Like other surgeries, it's covered by the insurance company. So, these fresh
guys are not afraid of cutting you open :) But again, that rarely happened,
otherwise, they won't be able to afford the premium.
