Even though both forms of myopia create a focal point in front of the retina, there are certain characteristic features which distinguish the two.
In axial myopia, there is no error in the refractive power of the eye; the main causative factor for axial myopia is the elongated eyeball. The refractive power in axial myopia is normally around about 60 diopters.
On the other hand, in the refractive form of myopia, the refractive power is usually higher than 60 D. This is strong enough to cause vision problems. It should, however, be noted that there is no alteration in ocular axial length in refractive myopia.
