Ophthalmologic apparatus, ophthalmologic control method, and program

An ophthalmologic control method comprising:

• performing positioning for a subject's eye and an apparatus body by projecting an index light flux on a cornea of the subject's eye and capturing a corneal reflection image with light reflected from the cornea of the subject's eye;
• detecting the position of the apparatus body when the positioning in a working distance direction is completed;
• causing a first acquisition unit provided on the apparatus body to acquire information about a radius of curvature of the cornea of the subject's eye;
• controlling a second acquisition unit provided on the apparatus body and configured to acquire information about an intraocular pressure of the subject's eye based on the detected position of the apparatus body and the acquired information about the radius of curvature of the cornea, in such a way as to set the proximity limit position in relation to the subject's eye to be a predetermined distance away from the cornea of the subject's eye in the working distance direction, regardless of the radius of curvature of the cornea of the subject's eye;
• and
• causing the second acquisition unit to acquire information about the intraocular pressure of the subject's eye at a predetermined position in a movable range, which is set in the working distance direction in such a way as not to exceed the proximity limit position.

An ophthalmologic apparatus comprising:

• a first acquisition unit configured to acquire information about a radius of curvature of a cornea of a subject's eye;
• a second acquisition unit configured to acquire information about an intraocular pressure of the subject's eye;
• and
• a determination unit configured to determine a proximity limit position of the second acquisition unit relative to the subject's eye in a working distance direction based on the acquired information about the radius of curvature of the cornea.

An ophthalmologic control method comprising:

• acquiring information about a radius of curvature of a cornea of a subject's eye;
• acquiring information about an intraocular pressure of the subject's eye;
• and
• determining a proximity limit position of a second acquisition unit, which acquires information about an intraocular pressure of the subject's eye, relative to the subject's eye in a working distance direction based on the acquired information about the radius of curvature of the cornea.
