My response will not address your concerns but I would like to comment. In order to better diagnose whether or not you have keratoconus you need to look at more than whether the curvatures of you cornea are steep. I would recommend you have a corneal topography performed. This test allows the doctor to map out in detail the exact topography (shape) or your cornea. Corneas with keratoconus tend to have a characteristic corneal topography. Keratoconus tends to cause a steeping in the cornea in the bottom 1/3 centrally located. This steepening is also associated with irregularity and thinning of the cornea over the steepened area. So, I would recommend going to see a corneal specialist and having him perform these tests. Hope this helped.
