CAA will treat each case on its own merit.... you MUST contact them and ask what your options are.... I did and gained my CLASS 1 in JUNE 08.
I had lasik to correct my astigmatism of -3.75 to -0.25 (CAA LIMIT ±2.00)
Please note that ASTIGMATISM is not the same as MYOPIA therefore the restrictions are different.... for example having a high astigmatism doesn't produce risk of retinal detachment which is why the myopia limit is imposed!
Hope this helps
