Abstract
A device for measuring eye characteristics, an operation device, and the coordinate origin and the coordinate axes of each eye are sufficiently related with one another. A measuring unit (111) measures eye optical characteristics based on a first light receiving signal from a first light receiving unit (23), and measures a cornea topography based on a second light receiving signal from a second light receiving unit (35). The measuring unit (111) also computes an ablation amount based on an aberration result.
