Ophthalmologic apparatus and method of examining eye to be examined

A method of examining an eye to be examined by an ophthalmologic apparatus including:

• a first left eye measurement optical system used for measurement of dimensional information in a front-back direction of a left eye to be examined;
• a second left eye measurement optical system used for measurement of a corneal shape of the left eye to be examined;
• a third left eye measurement optical system used for measurement of a refractive property of the left eye to be examined;
• a first right eye measurement optical system used for measurement of dimensional information in a front-back direction of a right eye to be examined;
• a second right eye measurement optical system used for measurement of a corneal shape of the right eye to be examined;
• a third right eye measurement optical system used for measurement of a refractive property of the right eye to be examined;
• and
• a control unit configured to control the first left eye measurement optical system, the second left eye measurement optical system, the third left eye measurement optical system, the first right eye measurement optical system, the second right eye measurement optical system, and the third right eye measurement optical system, and process measurement data obtained using each of the optical systems, the method comprising:
• a first measurement step of simultaneously performing the measurement using the first left eye measurement optical system and the measurement using the first right eye measurement optical system;
• a second measurement step of simultaneously performing the measurement using the second left eye measurement optical system and the measurement using the second right eye measurement optical system;
• a third measurement step of simultaneously performing the measurement using the third left eye measurement optical system and the measurement using the third right eye measurement optical system;
• a step of determining validity of the measurement data obtained by using the third left eye measurement optical system with the measurement data obtained by using the first left eye measurement optical system and/or the measurement data obtained by using the second left eye measurement optical system;
• and
• a step of determining validity of the measurement data obtained by using the third right eye measurement optical system with the measurement data obtained by using the first right eye measurement optical system and/or the measurement data obtained by using the second right eye measurement optical system.
