What exactly is the 'pre-operative refraction' that should not have been greater than +5.00? Is that the Sph values? As there are no limitations on astigmatism ect?
You should check directly with the CAA to be sure, but somewhere in the EASA medical documents, the refractive error is defined as the error in the worst median, so that means it's the sum of the sphere + astigmastism.
