I would go for a medical in spain. If they reject me I would try for medical U.K
It is possible that you can pass a First class medical because your eyes was within the renewal requirements before surgery.
It all depends on the licensing authourity.
Some doctors are nice and wants you to pass. They just check that you are a safe pilot.
Then there are doctors that are assholes. Remember one a doctor that wanted to fail me because I had to much earwax. I then called AMC and they just laughed. Anyway I got really scared with this and now everytime a go for a medical check I get "white coat hypertension"
