FltSgt88: If what I understand is correct, you astigmatism is 3.5/2.75.
I was in the same situation as you, my eyes astigmatism are 2.50 in one and 2.75 in the other.
I phoned the CAA on Wednesday to push my case but it was a no go for me and an end to obtaining a class 1 med and a dream of flying professionally

.
They treat each person on an individual basis though. I believe it all depends on your last numerous eye tests,if they are stable enough, if not then whats the change and is it suitable, all those kind of factors.
Let me know how you get on though, would be interested in hearing your end result. (Remember, an initial med fail isn't the end. Just call or visit and discuss it further and push your case. Good luck.)
