I got my eyes done in 1995 and I still have perfect vision. It's life changing and I am still amazed at the difference. Having had it I would gladly pay 4-5 times the price.
The most important thing is to have a stable prescription. If your eyes are changing then you may not be suitable.
You MUST get done by a competent and experienced practitioner. These are the guys who did my eyes:
www.newvisionclinics.com.au/newvision-clinics-director-dr-noel-alpins-am-receives-order-of-australia-medal/Noel Alpins had a great reputation when I got my eyes done. That was 14 years ago so I don't know anything about his reputation now but he's still in business so I guess that says something.
I know of two stuff ups. One was a chinese guy with really odd shaped eyeballs (really really flat ones). He had about a year of after care and ended up ok. My sister in law got a cheap job done at mate's rates and after several years of stuffing about she is back wearing glasses. I don't know of anybody going blind by having their eyes burned out of their head.
