摘要： The aberration and refraction power data of an eye to be examined obtained from a first light reception unit and cornea data of the eye to be examined are correlated with each other so as to be overlaid accurately. A first signal and a second signal are concurrently captured, and the optical characteristics and cornea shape of the eye to be examined are measured concurrently or almost concurrently. A measuring unit (111) measures dioptrical characteristics based on a first light reception signal from the first light reception unit (23), and measures a corneal topography based on a second light reception signal from the second light reception unit (35). A coordinates setting unit (112) converts signal in first and second coordinate systems, corresponding to the eye to be examined, included in the first and second reception signal into signal in reference coordinate systems respectively. A conversion unit (116) synthesizes the first and second optical characteristics of the eye to be examined obtained by the measuring unit (111) in association with each reference coordinate system formed by the coordinates setting unit (112). A measuring timing determining unit (117) determines the measuring timing of the first signal and the second signal to be subjected to measuring operation based on the first and/or second signal.
