Proach
If you are acceptable to CX but pending a medical issue resolution, CX will let you know. Sorry to tell you this, but you were not hired for reasons other than medical.
As an aside, there are statutory privacy laws in Hong Kong that prevent divulging any personal details (including medical) to anyone other than the concerned agency and the individual. If you injury was deemed to be health threatening in any way, the CX medical office would tell you.
The blood sample taken was used for lipid count (cholesterol) and HIV screening. Again, if something was found that you should know, you would be told.
To answer your question Skaz, US First Class is generally OK, but LASIK is an automatic disqualification. They're not looking for supermen, but healthy, no-risk pilots.
We have a couple of guys with installed pacemakers and a monocular (one-eyed) pilot. We also have a few world-class athletes (triathlon), a South Pole (on foot) explorer, Everest Summiters, Aerobatic Champions and enough former Red Arrows (RAF Aerobatic Team) to form several teams. There are also several world-class drinkers! Physical fitness is important here, but not the prime issue.
Good Luck.
