That is not all that myopic especially over 11 years. Most MDs use -5 or -6 for high myopia. Frankly I would get another opinion from an Eye MD ophthalmologist that does refractive surgery. You likely could have surface lasik (PRK) right now and if you have any significant changes down the road enhancement could be done.
If your "eye doctor" is an optometrist I have seen them refuse to refer because they would rather keep selling people glasses and are worried about losing the patient to the better trained Eye MD.
You can find a refractive surgeon near you at www.geteyesmart.org
