Abstract:
The ophthalmological device according to several exemplary embodiments includes an illumination system, an interference photography system, an anterior eye part photography system, a first optical path coupling element, and a control part. The illumination system projects illumination light that has been outputted from a light source onto an anterior eye part of an examined eye. The interference photography system is configured to photograph an interference pattern that is formed on the cornea by the illumination light. The anterior eye part photography system is configured to photograph the anterior eye part onto which the illumination light is being projected. The first optical path coupling element couples the optical path of the interference photography system and the optical path of the anterior eye part photography system. The control part superimposes an interference image that has been acquired by the interference photography system onto an anterior eye part image that has been acquired by the anterior eye part photography system and makes a display part display the superimposed images.
