摘要:
Disclosed is an ophthalmology device capable of accurately measuring the shape of a cornea. A projected image forming part (13) projects a plurality of bright spots arranged approximately circularly onto the cornea of an eye (E) to be examined. A TV camera (56) captures an image of the cornea onto which the bright spots are projected. A storage part (70) stores bright spot image position information (71) in advance. The bright spot image position information (71) represents the positions of the bright spot images shown in a nonastigmatism captured image obtained by capturing, by means of the TV camera (56), an image of a nonastigmatism cornea model eye onto which the bright spots are projected. A calculating part (80) corrects, according to the bright spot image position information (71), the positions of the bright spot images shown in the cornea captured image obtained by capturing, by means of the TV camera (56), an image of the cornea of the eye (E) to be examined onto which the bright spots are projected. Further, the calculating part (80) calculates an evaluation value of the shape of the cornea on the basis of the corrected positions of the bright spot images.
