Beamish (and others) I spent quite a while scaring myself reading all the scare stories on t'internet, but I pretty sure that with a reputable company and proper aftercare it's safe. I used Optical Express who are probably the biggest in the business, so can afford all the latest kit and aren't going to risk their rep by doing innapropriate treatment.
I paid £3400

which is right at the top end of their price list. Starts at £500 per eye, but add another £400 each if you have a high prescription like me. The preferred technique now is 'wavefront' which measures all your eye surface and treats each part appropriately, rather than just doing a single prescription for the whole eye. Add £500 per eye for this.
Preferred method for cutting the flap which has to be lifted to allow treatment (are you all still with me here?

) is by laser rather than mechanically. This is vital for a high prescription like mine, as it allows a flap thickness (stop sniggering at the back) about half (100 microns) that of the mechanical method (180 microns). Add £300 per eye for this.
A few more stats: your eye is around 550 microns thick and they remove around 15 - 17 microns per diopta, so my -8 prescription required 120-130 microns to be torched. This is why the extra 80 microns of flap (see above) is so vital. Around 3% of patients need a 'top-up' treatment later, though this is higher with a higher prescription. This can be done around a year later. Guideline settling in time is one month per diopta, though you'll be 98% of the way there within a few days of the op.
So yeah, I paid the price of a mint Storm for it, but as VTR girl says, it can be a life changing experience. I've probably been a bit complacent about it, as I've worn contact lenses for years, so it doesn't feel that different to me. But out walking the dog last night I looked up at the stars (yep, even in the middle of Leicester) and realised just what a bloody miracle it is.
