Hi Phil, I have just read your comments on this site and just wanted to say that I was -8 in both eyes with around a -3 astigmatism giving a whopping -11 combined refractive error. I had LASIK treatment 2 days ago at Accuvision. They have some equipment called a Wavefront Analyser (only equipment of its type in the country apparently) that they say has helped people like you in the past, it may be worth giving them a call.
