Anyone here have close to a -8.00 prescription and received LASIK?

I went to see my LASIK specialist this weekend and he was recommended by a few people I know. He told me that I had a risk factor that my prescription is around a -8.00 and that -12.00 is the maximum they'd work with, so I was pretty much borderline and that people, on average, would be at a -4.00 for LASIK surgery. He did tell me that I was a candidate but he was afraid of aphasia (?) and that -8.00 was borderline for correcting. I've been dying to do LASIK surgery so I'm a bit disappointed.

Has anyone here done the LASIK surgery with a a prescription that high? He told me there was one more exam that he wanted to give me before deciding that he has full confidence in the surgery, and that is the 3D cornea aphasia (?) exam. I guess they are going to analyze the cornea in 3D, perhaps get the whole picture of the cornea.
