First off, I never said that an internationally trained ophhtalmologist could practice in the states without additional training.
Secondly everyone I met that is an IMG, did indeed pass all steps and CSA (now step 2 CS), BUT did not go for ophtho residency, but for fellowship
I never mentioned anything about certification or re-certification.
I also never doubted the fact that it is not easy to get certified in the US.
Nevertheless, I am not entirely certain that you need to do everything all over again. Just with the steps (I, II and III) I believe you get a partial license. Additionally I am not surehow but you can also get an unrestricted license once you fill some specific criteria which I am not up to date with, but from what I understand do not necessarely include full ophtho training in the US.
Finally, where I come from, no one has ever abandoned a good career to do residency all over again. Even the studying of the steps is a huge burden once you have been out of med school for more the 4 years...
Finally, no one will address the matter of people in this message board stating that it is an advantage not having prior residency training in an other country in order to match...
It was in an faq regarding what IMGs should do to match in ophtho.
