PROBLEM TO BE SOLVED To provide a new method of alignment of an ophthalmologic apparatus.An ophthalmologic apparatus includes an optical system including an objective lens and acquiring data by scanning an area including at least a part of a front face of a subjects face using an OCT via an objective lens, A driving unit which relatively and three-dimensionally moves the eye to be examined and the optical system, an analyzing unit which specifies a three-dimensional position of at least a part of the area based on data collected by the optical system, an objective lens Dimensional shape information of the eye to be inspected on the basis of the three-dimensional position specified by the analysis unit a calculation unit which obtains a relative movement amount between the eye to be inspected and the optical system based on the three-dimensional position specified by the analysis unit A determination unit for determining whether or not the eye to be examined and the optical system after relative movement by the amount of movement are close to each other within a predetermined distance based on the information, Control the drive based on the dimensional position It comprises a control unit for relatively moving the subjects eye and the optical system by.(FIG.【課題】眼科装置のアライメントの新たな手法を提供する。【解決手段】眼科装置は、対物レンズを含み、OCTを用いて被検者の顔の前面の少なくとも一部を含む領域を対物レンズを介してスキャンしてデータを収集するための光学系と、被検眼と光学系とを相対的にかつ3次元的に移動する駆動部と、光学系により収集されたデータに基づいて上記領域の少なくとも一部の3次元位置を特定する解析部と、対物レンズの3次元形状情報をあらかじめ記憶する記憶部と、解析部により特定された3次元位置に基づいて被検眼と光学系との相対的な移動量を求める算出部と、3次元位置と3次元形状情報とに基づいて、上記移動量だけ相対移動された後の被検眼と光学系とが所定の距離以内に近接するか否かを判定する判定部と、判定部による判定結果に応じて、3次元位置に基づいて駆動部を制御することにより被検眼と光学系とを相対移動させる制御部とを含む。【選択図】図5
