<P>PROBLEM TO BE SOLVED: To obtain a cornea shape in a wide range from a cornea center part to a cornea peripheral part. <P>SOLUTION: The cornea shape measuring apparatus for projecting an index for measuring the cornea shape in a wide range from the center part to the peripheral part of the cornea of an eye to be examined and measuring the cornea shape on the basis of the image of the index for measuring the cornea shape, which is projected on the cornea, comprises: a storage means for storing first measurement data measured by fixing a fixation mark on the eye to be examined in the state of turning the face of a subject to the front to a measurement optical system and also storing second measurement data measured by fixing the fixation mark on the eye to be examined in the state of turning the face of the subject to an oblique direction to the measurement optical system so as to obtain the measurement data of the cornea part which can not be obtained by the first measurement data; and an arithmetic means for combining the first measurement data and the second measurement data stored in the storage means and computing cornea shape data for which the defective areas of the respective data are complemented. <P>COPYRIGHT: (C)2007,JPO&INPIT |
