Terminology Explanation Spectacle refraction The spherical and cylindrical combination required, at a stated vertex distance, to correct the patient's ametropia Ocular refraction
The spectacle refraction adjusted by compensating for the back vertex distance (BVD) Spectacle astigmatism Can occur either from corneal and/or lenticular astigmatism.
Broadly speaking, there are four subcategories when comparing ocular refraction to the 'K' readings, namely:
Here, the corneal astigmatism corresponds to the ocular refraction, therefore, spherical RGP lenses would provide a suitable option.
