PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of accurately measuring an intraocular distance of an eye to be examined.SOLUTION: An interference optical system 80 divides a light from a first light source into a reference light and a measurement light, irradiates the measurement light onto an eye to be examined, generates an interference light between the return light and the reference light, and detects the generated interference light. A first focusing lens 85 can move along an optical path of the measurement light. A second focusing lens 89 can be inserted into/extracted from the optical path of the measurement light. A focus control unit executes movement control for the first focusing lens 85 so that the intensity of an interference signal corresponding to the retina or cornea rear face included in first detection data on the interference light obtained in a state in which the second focusing lens 89 is retreated from the optical path, or an interference signal corresponding to the crystalline lens front face included in second detection data on the interference light obtained in a state in which the second focusing lens 89 is inserted into the optical path becomes highest. An intraocular distance calculation unit acquires the optic axial length or the corneal thickness on the basis of the first detection data, and acquires the anterior chamber depth on the basis of the second detection data.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】被検眼の眼内距離を高精度に測定することが可能な眼科装置を提供する。【解決手段】干渉光学系８０は、第１光源からの光を参照光と測定光とに分割し、測定光を被検眼に照射し、その戻り光と参照光との干渉光を生成し、生成された干渉光を検出する。第１合焦レンズ８５は、測定光の光路に沿って移動可能である。第２合焦レンズ８９は、測定光の光路に対して挿脱可能である。合焦制御部は、第２合焦レンズ８９が光路から退避されている状態で取得された干渉光の第１検出データに含まれる網膜又は角膜後面に相当する干渉信号、又は第２合焦レンズ８９が光路に挿入されている状態で取得された干渉光の第２検出データに含まれる水晶体前面に相当する干渉信号の強度が最も高くなるように第１合焦レンズ８５の移動制御を行う。眼内距離算出部は、第１検出データに基づいて眼軸長又は角膜厚を求め、第２検出データに基づいて前房深度を求める。【選択図】図１
