My opinion is the risk profile is materially different.

After having a minor medical procedure go poorly at a "Westerner" Hospital in Asia my motivation for corrective eye surgery changed from economic to risk mitigation. The totality of the services provided in the US meant a much lower risk procedure for a fairly insignificant increase in cost.

Caveat: Avoid those clinics in the US that are well advertised and want to put you on a payment plan. Their business model is more about profit than your eyes. In other words, its wise to continue DD even if a US clinic is chosen.

Cheers
