Lasek
Consider it very carefully - I'm a heli pilot and doctor and had Lasek....and the previous posts are mostly accurate...but the results for some people are unpredictable especially when it comes to night vision. It is not uncommon to be left with less good night vision than pre-surgery, especially halos (as I have mildy). Risks of major compleciatipons are extremely low, but a small percentage will need a re-do in the months after the initial procedure to gain an optimum result.
Also, in the years following surgery it is again not uncommon for near vision to detriorate after correction for short sightedness, often leading to the need for glsses to see close-up...so you could in theory substititute one visual defect for another, not necessarily to the same degree though. The overall results also tend to drift with age and the passing of time as the lens becomes less flexible.
I have no regrets about undergoing the Lasek (especially with young kids around), but for a CPL/ATPL upon whose career eyesight will depend, research long and hard - pick your surgeon very carefully indeed, it can make a significant difference in long term outcome.
