My husband recently had 4 surgeries in his eyes to help correct and stop Keratoconus and he is due to be asked for a medical exam very soon. I know he will have 90 days to complete their request. Should we do it right away or wait for a bit until his eyes have recovered more? Are his eyes going to be big factor in determining if he is healthy or not or are they looking for different things? Could they use his eyes as an excuse not to let him immigrate to Canada?
