PROBLEM TO BE SOLVED: To provide a novel technique for accurate positioning of an optical system and an eye to be examined while avoiding contact.SOLUTION: An ophthalmologic apparatus comprises: an optical system for acquiring data of an eye to be examined a drive part for relatively moving the optical system and the eye to be examined in an optical axis direction of the optical system a distance identification part for repeatedly identifying a distance between the optical system and the eye to be examined and a control part for updating a control condition to the drive part based on the distance which is identified by the distance identification part, and controlling the drive part based on the updated control condition for relatively moving the optical system and the eye to be examined.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】接触を回避しつつ、光学系と被検眼との高精度な位置合わせを行うための新たな技術を提供する。【解決手段】眼科装置は、被検眼のデータを取得するための光学系と、光学系と被検眼とを光学系の光軸方向に相対的に移動する駆動部と、光学系と被検眼との間の距離を繰り返し特定する距離特定部と、距離特定部により逐次に特定された距離に基づいて駆動部に対する制御条件を逐次に更新し、更新された制御条件に基づいて駆動部を制御することにより光学系と被検眼とを相対移動させる制御部とを含む。【選択図】図1
