I had exactly the procedure you’re thinking about at Optical Express and it has wrecked my night vision. My vision is great during the day – good enough to drive without glasses – but at night I get fringeing and halos around anything bright (like the TV) and I struggle to do night rides.
The problem is (I have learned since) is that I have large pupils (7mm) and when they open up to full size they let light in that has passed through the transition area between the reshaped and original parts of my cornea causing a blurred image to be overlayed on the sharp image. No-one mentioned I had large pupils and so were at greater risk before the op.
My advice – chack your pupil size is well within the average before having it done as you can’t reverse it.
