So for me it seems quite clear that there is a way around this in Japan as well, just as in China. I think these recruiters should be made aware of such possibilities, as this would include quite many suitable and competent candidates for the screenings. Or maybe they already know this, but won't bother going through the process, so it is easier just to say "no way Jose" to anyone with a history of Lasik.
As I understand there is indeed an approval procedure for this, but I don't really know of anyone that has actually done it, it seems to me that a strong backup from the company that wants to hire you would be crucial for the case to case criteria, how much would they be willing to fight for you with the JCAB I just don't know, they don't do a lot of arguing with the JCAB around here if you know what I mean
