JBay1,
The best info I could get in regards to LASIK for aircrew was this from DFR:
"Candidates applying for aircrew positions who have undergone LASIK may be acceptable”, “The specialist report must confirm that the candidate has undergone contrast sensitivity testing and must report the results. Contrast sensitivity can be undertaken with the Pelli-Robson chart or any other 5% contrast sensitivity chart used by the Ophthalmologist. Contrast testing and symptom discussion should not be undertaken until 3 months post surgery for myopia and 6 months post surgery for hypermetropia”.
“Candidates who do not meet the AVR standard are not to be advised to undergo surgery as a means of entry….Defence does not advocate surgery as a means of entry: undergoing surgery does not guarantee entry”.
Read into all that as you will, but be aware that LASIK may disqualify you for aircrew indefinitely. I have heard of some great results from PRK however.
