I had a bit of a read on the CAA's SRG medical section.
If you are "just outside" the limits, they recommend you contact them prior to surgery.
They are also reviewing the requirements if only 1 eye is outside the limits.
There is another way. The initial JAA class 1 requirements are stricter than the renewal limits. If you hold a class 1 from another ICAO state, then you "might" be able to get a JAA Class 1 under the renewal requirements.
Good luck.
