Method for determining total refracting power of cornea of e.g. astigmatic eye, involves determining refracting power of cornea front side, and determining central thickness of cornea based on total refracting power of cornea

摘要

The method involves measuring radius of front side and rear side of cornea. Refracting power of the cornea front side is determined. Central thickness of the cornea is determined based on total refracting power of the cornea. The refracting power of the cornea front side, the refracting power of the cornea back side, the radius of the cornea front side, radius of the cornea back side, refraction index of air, refraction index of the cornea, refraction index of chamber water and central thickness of the cornea are defined. Radii of the refracting powers of the cornea are indicated in diopters.
