PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus and an operation method therefor, capable of measuring an eye characteristic of a subject's eye even when the eye is a diseased one.SOLUTION: An ophthalmologic apparatus comprises； a target projection optical system in which a first luminous flux emission unit and one of first lenses are arranged so as to freely move back and forth along a first optical axis； a measurement pattern projection optical system in which a second luminous flux emission unit is arranged so as to freely move back and forth along a second optical axis； a light-receiving optical system including a second lens arranged so as to freely move back and forth along a third optical axis； an interlocked movement mechanism for moving the one, the second luminous flux emission unit, and the second lens in a parallel direction in parallel with the first optical axis in an interlocked manner； a movement control unit for executing movement processing of moving the one on the first optical axis； a stop operation reception unit for receiving a stop operation for stopping the movement processing； a stop control unit for stopping the movement processing； and a focusing position determination unit that on the basis of a stop position of the one stopped by the stop control unit, determines the one's focusing position for focusing a target luminous flux on the eyeground.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2020,JPO&INPIT【課題】疾患を伴う被検眼であってもその眼特性を測定することができる眼科装置及びその作動方法を提供する。【解決手段】第１光束出射部及び第１レンズの一方が第１光軸に沿って進退自在に配置されている視標投影光学系と、第２光束出射部が第２光軸に沿って進退自在に配置されている測定用パターン投影光学系と、第３光軸に沿って進退自在に配置された第２レンズを有する受光光学系と、一方、第２光束出射部、及び第２レンズを、第１光軸に平行な平行方向に連動して移動させる連動移動機構と、一方を第１光軸上で移動させる移動処理を実行する移動制御部と、移動処理を停止させる停止操作を受け付ける停止操作受付部と、移動処理を停止させる停止制御部と、停止制御部により停止された一方の停止位置に基づき、視標の光束を眼底に合焦させる一方の合焦位置を決定する合焦位置決定部と、を備える。【選択図】図５
