Thought my two cents here are worth a little more......
I was -8/-9 and had surgery 5 years ago. Had the surgery done at Yale University in New Haven, CT. I decided to go to a high end provider since I was at the outer end of the spectrum for what could be done at the time. I'm glad that I did since I had to have two surgeries on one eye due to some complications. I don't know if the procedure/brand is still around, but it was called LADAR.
Pros: went from god-awful thick glasses to being able to get by without any! it's a change of life. absolutely.
Cons: left me with a stigmatism in one eye, but the other is near perfect. my vision is 20/25 w/stigmatism in one eye and 20/20 in the other. I've always had starburst issues, but they've become much worse. I do wear glasses with a super AR coating and a slight prescription to help the stigmatism in the one eye.
Overall, not perfect, but an amazing difference. Hope that helps out.
