if you want to take any risk out of the whole process, go with these guys. They are fantastic, I haven't a negative thing to say about them.
I had my eyes done 6 months ago. One eye is now 20/20 perfect. The other still has a slight stigmatism, so a bit blurry.
At my 6 month review, Mr Pillai said he'd get me back in (all included in the price) for an enhancement. Both eyes are now 20/20; better than when I wore glasses.
