I had LASIK done 3 years ago.
The concern over the halos is real.
The first few months were real bad for me, night time driving was a PITA.
Every headlight had a huge halo.
LED lights were hard to look at, they are far worse then any other kind of light.
I was on a fishing trip the 2nd week after it was done, we were using lighted bobbers night fishing, mine looked 1 foot in diameter when it was in the water.
I was pissed at the time.
I went in for my first check up and the ophthalmologist who did my eyes assured me it will go away, and had a chart were you could show how bad of a halo you were getting.
He told me it was normal not to worry about it.
Funny how they don't show you the chart before you have the procedure done
It did get a lot better after 6 months but for me it never did fully go away.
I have dry eye, the halos are gone if I can manage to keep drops in them.
I notice it if I work to many hours, then drive at night.
LEDs can still give me problems.
I never have had a problem natural light.
But I never tried to look though a telescope at night when I was going though the worst halos.
If I could go back in time knowing what I know now I would still get it done.
I was at a point were contacts would drive me nuts.
Glasses just plain suck, I had them for over 35 years.
Its the simple stuff.
Being out in the rain, coming inside from the cold and your glasses fog up.
Swimming, falling asleep with the TV on.
As far as the procedure its a snap, no problem.
When they slice your eye it smells like you singed your hair.
Its over fast, then it feels like you have sand in your eyes for a couple hours.
Take a nap, wake up and WOW you can see.
