To provide an ophthalmologic apparatus and a program for an ophthalmologic apparatus that can perform calibration with a simple configuration.SOLUTION: An ophthalmologic apparatus for measuring an eye to be examined comprises an interference optical system for acquiring a first interference signal by making first reflected light, in which measurement light emitted from a light source is reflected by the eye to be examined, and reference light corresponding to the measurement light interfere with each other, and calculation means for correcting a measurement result based on the first interference signal by using a second interference signal obtained by the interference between second reflected light, in which the measurement light is reflected by an optical component constituting the interference optical system, and the reference light.SELECTED DRAWING: Figure 2 【課題】 簡単な構成で校正を行える眼科装置及び眼科装置プログラムを提供することを技術課題とする。【解決手段】 被検眼を測定する眼科装置であって、光源から出射された測定光が前記被検眼によって反射した第１反射光と、前記測定光に対応する参照光とを干渉させて第１干渉信号を取得する干渉光学系と、前記干渉光学系を構成する光学部品によって前記測定光が反射した第２反射光と、前記参照光とが干渉して得られた第２干渉信号を用いて、前記第１干渉信号に基づく測定結果を補正する演算手段と、を備えることを特徴とする。【選択図】 図２
