No way to tell since you have cataracts. Cataracts create increasing myopia but do not make the eye longer or the corneal more curved. It depends on your refraction prior to the development of the cataracts. Your ophthalmologist can examine your eye, measure the length and tell you.
True high myopia is due to a long eye.

OK..then..assuming cataracts weren't involved and we have only 'long eye', would -5 or -9 diopters be considered high myopia? What would be considered "high" in this case? Thanks.
Less than 3 diopters is mild; 3 to 6 diopters moderate myopia and greater than 6 diopters high myopia.
