I want to have revision eye surgery at a large ㅇㅇㅂ hospital at the end of March next year..
Since it’s October now.. I have about 5~6 months
I’m not sure whether it would be better to go in advance and make a reservation... or to book when there are about 3 months left...
I’m worried the hospital might say it’s not possible if I try to book too far in advance....
