I had Lasik some years ago and it was performed poorly by the doctor. I wanted to go to the best doctor in my area but they redirected me to another doctor who was a rank amateur. Back then there was only one size of laser which was too small for my bigger than average eyes, thus the doctor should have warned me that the glare effect would have been even worse than average. Also, you are supposed to keep your eyes perfectly still while the laser is operating but a lot of people get unconsciously nervous and tense and their eyes go upwards causing "decentration" with the after effect of having, permanently" double and or multiple vision. That is not too much of a problem for modern machines because they have a tracking device that automatically shuts off until your eyes are in alignment. My machine did not have that tracking device so now, especially at night time, I see multiple-8 or so-traffic lights.
In order to fix my eyes now I would need to have a cornea transplant due to the fact that I have had multiple operations (unsuccesful) in one eye and everytime you perform another operation your cornea gets thinner.
My suggestion is that you go to the best doctor in the field, even if you have to travel some, and ask questions about his machine as well as getting from the library any books on the subject.
If you are near to the Los Angeles area the best doctor, in the nation, who was part of the research team for Lasik, is Dr. Robert Maloney. Good luck and be careful.
