i'm also looking into this,

the eyes need to have stopped growth, you need to fit and healthy, vision needs to be stable for about 2yrs and comes in around 4-5grand depending where and who does it,

not covered by private healtcare but they do cover the costs of the room, 10-15 mins on each eye you can smell the eye tissue burning. leave looking like a cheap pirate with double eye patches and leave them on for half a day.

next day should see 20/20 vision but they say the eye can feel "gritty and slighty dry" for anywhere up to 6 months as the worst case.

my mum had it done and while it corrected her long disatance vision to 20/20 she needed to get reading glasses in 2 days after the operation. apparently this is a side affect in some cases.
