I expect this is not what you want to hear but a quick look in AP1269a (the RAF manual of medical fitness) will tell you that your history of epilepsy will disbar you and a history of laser eye surgery will also disbar you.
I'm also sorry to say that the attitude that rules can be ignored because you feel they are petty will also disbar you from being a RAF officer, and probably an airman.
To fly high performance aircraft like Eurofighter requires 100% fitness, the edge of the human performance envelope is not a place to be if you have a history of fits, however they may have been caused. We also require 100% integrity in what is after-all a military environment.
Best wishes for the future
