As far as I am aware (keeping in mind I am a mere SPL, minion if you will) a class 1 med cert should be the end of it. Any airline who disqualifies you on medical grounds aint following the JAA med rules. A class 1 is a class 1. You satisfy all the med requirements stated by our Highest Power, the JAA. I've get a -3 and passed my eye exam no probs.
I think airlines are much stricter when they are taking you on as a cadet. But when it comes as to applying, they (I say this lightly, and have nothing to back it up!) cannot discriminate against you.
....but keep in mind also. I think that you cannot fly for 12 months after such an eye operation...I'm sure I have seen that somewhere....just check that one out.
Hope my vague info was useful...
