An ophthalmologic device measures corneal curvature and ocular refractive power of the eye by imaging the positions of a plurality of bright points which result from plural light rays and by imaging a predetermined pattern of the eye. The ophthalmologic device includes a frame memory to store picture data of the eye which has been imaged by a video camera. The picture data in memory is classified into bright spot regions in which bright spots are present one at a time, a corneal reflected image region in which a reflected image from the cornea of a predetermined pattern is projected into the fundus of the eye, and mask regions in which the bright points and the corneal reflected image are not present. The picture data having a luminosity greater than a predetermined threshold value is stored for later calculation of a centroid of the bright points to measure the corneal curvature of the eye.
