  • Method for determining the total refractive power of the cornea of an eye
    Patent number: 9622659
    Abstract: A method for determining the total refractive power of the cornea is based on a combination of keratometric or topographic measurements using the measured values obtained from depth scans or sectional images. The radius (Ra) of the front side of the cornea is ascertained keratometrically or topographically, the radius (Rp) of the rear side of the cornea is determined from depth scans or sectional images, and the refractive power (Ka) of the front side of the cornea, the refractive power (Kp) of the rear side of the cornea, and the total refractive power (K) of the cornea are determined. The method is used to determine the total refractive power of the cornea of an eye and is not just applicable to eyes with normal vision but in particular also to astigmatic eyes.
