Patent ID: 8220927

Claim:
A method of determining and selecting a contact lens using an opthalmological device for examining eyes, wherein the opthalmological device comprises a keratometer and an autorefractometer as well as data processing means, whereby a refractive power of an eye and a topography of a cornea of the eye are determined using the autorefractometer and the keratometer, respectively, so that refraction data describing the refraction of the eye examined are obtained by the autorefractometer, and whereby topographic data describing the topography of the cornea of the eye are obtained by the keratometer, wherein the method comprises the steps of: (a) using the data processing means to calculate contact lens data on the basis of the refraction data and the topographic data obtained by the autorefractometer and the keratometer, respectively; and (b) selecting a contact lens from a database of the opthalmological device based on the calculated contact lens data.
