Ophthalmology apparatus and method of controlling ophthalmology apparatus

摘要

An ophthalmology apparatus includes: an aberration measuring unit configured to measure an aberration of an eye to be examined on the basis of returned light from the eye to be examined irradiated with measurement light, and a change unit configured to change a size of an irradiating area in the aberration measurement unit to be irradiated with the returned light.

1. An ophthalmology apparatus configured to irradiate an eye to be examined with measurement light, to correct an aberration of returned light from the eye to be examined with a correction unit, and to acquire an image of the eye to be examined based on the corrected returned light, the apparatus comprising:
a light split unit configured to split the corrected returned light into light for aberration measurement and light for forming an image of the eye to be examined; a change unit configured to change a beam diameter of the light for aberration measurement split by the light split unit; an aberration measurement unit configured to measure an aberration of the light for aberration measurement having passed through the change unit and having the beam diameter changed by the change unit; and a display control unit configured to control a display unit to display a display form indicating an irradiating area on the aberration measurement unit which is irradiated with the light, wherein the change unit is disposed in an optical path of the light for aberration measurement between the light split unit and the aberration measurement unit, and wherein the light for aberration measurement is incident on the aberration measurement unit after passing through the change unit.
