PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus capable of observing reflected light having sufficient strength from a crystal lens and identifying the position of the crystal lens accurately.SOLUTION: An ophthalmologic apparatus comprises: a light source 12 measurement optical systems (24, 28, 34, 30, 40, 46, 48) for irradiating an inside of an examined eye with light from the light source and guiding the reflected light reference optical systems (24, 22) for irradiating a reference surface with the light from the light source and guiding the reflected light a light receiving element 26 for receiving interference light in which the reflected light guided by the measurement optical systems and the reflected light guided by the reference optical systems are synthesized and an arithmetic unit for identifying a position of a measured portion of the inside of the examined eye on the basis of the interference light received by the light receiving element. The measurement optical systems comprise incident angle changing means 46 for changing an incident angle of the light, with which the examined eye is irradiated, to the examined eye within a predetermined angle range with respect to a visual axis of the examined eye.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】 水晶体から充分な強度の反射光を観察することができ、水晶体の位置を精度良く特定することができる眼科装置を提供する。【解決手段】 本願の眼科装置は、光源12と、光源からの光を被検眼の内部に照射すると共にその反射光を導く測定光学系(24,28,34,30,40,46,48)と、光源からの光を参照面に照射すると共にその反射光を導く参照光学系(24,22)と、測定光学系により導かれた反射光と参照光学系により導かれた反射光とが合成された干渉光を受光する受光素子26と、受光素子で受光される干渉光から、被検眼内部の測定対象部位の位置を特定する演算装置とを有している。そして、測定光学系は、被検眼に照射される光の被検眼への入射角を被検眼の視軸に対して所定の角度範囲で変更する入射角度変更手段46を有している。【選択図】 図1
