You would have to have a consultation. It is not just as simple as just measuring your prescription. During laser surgery the surgeon slices a layer off the front of your cornea (in very simple terms) so, the thickness of your cornea is a huge factor.ie. you could have a very thin cornea but only have a small prescription and be unsuitable for surgery or you could have a higher prescription and be suitable because your cornea is thick.I feel the answer will be no because your true prescription will be stronger than your contact lens prescription and over a -9 is really pushing it but you'll never know unless you see some surgeons. It is cosmetic surgery so treat it like that, See several surgeons and get several opinions, don't opt for the cheapest, opt for the one with best results and recommendations. There are other types of refractive surgery for example cataract surgery (without actually having a cataract!) so there may be an option for you
