I got a laser-only procedure done about 5 years ago now, and it's been the best decision of my life. I had halos for about 6-12mo, but I also had minor halos before the surgery too - so I really haven't noticed much of a difference.
One thing you should either really really do, or really really don't do (I still can't decide) is walk the Vegas strip at night the day after surgery like I did. You will have major halos/starbursts at that point, and it's the closest to a random private laser show as I've ever gotten in life. I suppose drugs may be less risky and cheaper though...
Were they all treated at the same local clinic perchance? The problem might be with the clinic or doctor.

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