Matt, I had it done a couple of years ago. I wrote a pretty detailed description of the experience here somewhere about June or July time.
I was a +3.5 correction on both eyes and needed specs for just walking around. Nowadays the treatment has settled down to me using a set of +1.75 - +2.00 off the shelf specs for reading and close work only, other than that my life is spectacle free.
I did loads of research before I went and I even turned one clinic down after the consult, make sure they are using Wavefront Lasik - google it before you go for your consult. Also be aware that at some of the clinics the term 'Customer Adviser' should be changed to 'Commision Based Sales Agent'.
Afterwards, I wore some clear skydiving goggles immediately after the op and around and about the garden for a few days afterwards. I also wore a snorkelling mask when taking showers for a couple of weeks afterwards. Call me paranoid - but your eyeball is cut open and you can get an infection, so better safe than . They tell you that everything settles down in a few weeks but I was still sensitive to air pressure and aircon for about a year afterwards, as for night blindness - I have no noticeable difference its still ok.
Other than that mate, its a doddle, go for it. If you want to ask me anything from a patients point of view you are welcome to PM me.
