PROBLEM TO BE SOLVED: To provide a technique achieving miniaturization of an ophthalmic apparatus capable of performing a plurality of measurements performed before a cataract operation.SOLUTION: The ophthalmic apparatus according to an embodiment includes an interference optical system and an eyeball information calculation unit. The interference optical system divides light from a light source into reference light and measurement light, guides the reference light to a first mirror unit and a second mirror unit that can set the reference light in reference optical path lengths different from each other, irradiate an eye to be examined with the measurement light, and moves at least one of the first mirror unit and the second mirror unit in an optical axis direction, so that first interference light between return light from the eye to be examined and the reference light via the first mirror unit and second interference light between the return light and the reference light via the second mirror unit are simultaneously detected. The eyeball information calculation unit obtains eyeball information representing structure of the eye to be examined from detection results of the first interference light and the second interference light.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】白内障手術前に行われる複数の測定が可能な眼科装置の小型化を実現するための技術を提供する。【解決手段】実施形態に係る眼科装置は、干渉光学系と、眼球情報算出部とを含む。干渉光学系は、光源からの光を参照光と測定光とに分割し、参照光を互いに異なる参照光路長に設定可能な第１ミラーユニット及び第２ミラーユニットに導き、測定光を被検眼に照射し、第１ミラーユニット及び前記第２ミラーユニットの少なくとも一方を光軸方向に移動させることにより被検眼からの戻り光と第１ミラーユニットを経由した参照光との第１干渉光、及び戻り光と第２ミラーユニットを経由した参照光との第２干渉光を同時に検出する。眼球情報算出部は、第１干渉光及び第２干渉光の検出結果から被検眼の構造を表す眼球情報を求める。【選択図】図３
