I would be a bit difficult to give source on my personal friends and my dad, it's an anecdote :P Treat it like everything on the internet said by a random person - with caution. Just because everyone I know who got LASIK done has halos doesn't mean it's commonplace - could be just a coincidence.

Findings from the Casey Eye Institute:

It's also worth noting that LASIK has improved drastically over the past 10 years. Bladeless procedures, wavefront imaging, femtosecond lasers, etc.
