I got lasik done last summer. and it took 9 months for the night halos to go away. I also kept having dry eyes so I would constantly need to put drops in. but that ceased as well.
I'm near sighted. pre lasik, I had incredible close up vision. I use to be able to see the writing on capacitors etc. but Post lasik, my close up vision completely vanished. Thankfully apple has a near feature in the accessibility area that makes your iphone into a excellent magnifier!
I have no regrets no 16 months post surgery!
PS. Last tip, if your surgeon accepts "Care Credit", make sure you pay it off in a year bc those bastards charge 26.99% interest. They tried to tack on $1000 of interests on my card but they agreed to let me pay it off by decemeber and once i do, they'll remove all of the finance charges bc of harvey.
