I did it over 2 years ago now. One of the best decisions I ever made.
Can I ask where you had it done?
Hans it is a very effective service right across the board and is very succesful.
I work in Optics and there are several good companies you could look at Laser Vision Europe on Harley Street in London have a good reputation, Optimax are also good and Ultralase.
Most commercial one is Optical Express who obviously advertise on the tele etc and are buying most of the smaller laser companies up. They again have a good reputation but also have a reputation for being money grabbing bastards, but would definitely recommend doing it. Yet to hear a bad review about it.
