PROBLEM TO BE SOLVED: To provide an ophthalmologic apparatus and a cornea shape measurement method used therein capable of highly accurately measuring a cornea shape of a subject eye.SOLUTION: The ophthalmologic apparatus comprises: a pattern light projection optical system； a cornea-captured image acquisition unit for acquiring a cornea-captured image which includes a pattern light reflection image； a projection control unit for changing the light amount of pattern light projected onto the cornea at least one or more times； an acquisition control unit for causing the cornea-captured image acquisition unit to reexecute the acquisition of the cornea-captured image each time the light quantity of pattern light is changed； a luminance value detection unit for detecting a luminance value of the reflection image from the cornea-captured image acquired for each light amount of pattern light； a selection unit for selecting, from among cornea-captured images by light amount, a cornea-captured image best suited for detecting a site for each site within the reflection image on the basis of a detection result of the luminance value detection unit； a site detection unit for detecting a site from the cornea-captured image selected by the selection unit, for each site； and a cornea shape calculation unit for calculating the cornea shape of the subject eye.SELECTED DRAWING: Figure 10COPYRIGHT: (C)2020,JPO&INPIT【課題】被検眼の角膜形状を高精度に測定することができる眼科装置及びその角膜形状測定方法を提供する。【解決手段】パターン光投影光学系と、パターン光の反射像を含む角膜撮影像を取得する角膜撮影像取得部と、角膜に投影されるパターン光の光量を少なくとも１回以上変化させる投影制御部と、パターン光の光量が変化されるごとに、角膜撮影像取得部による角膜撮影像の取得を再実行させる取得制御部と、パターン光の光量別に取得された角膜撮影像から、反射像の輝度値を検出する輝度値検出部と、輝度値検出部の検出結果に基づき、反射像内の部位ごとに、部位の検出に最適な角膜撮影像を、光量別の角膜撮影像の中から選択する選択部と、部位ごとに、選択部により選択された角膜撮影像から部位の検出を行う部位検出部と、被検眼の角膜形状を演算する角膜形状演算部と、を備える。【選択図】図１０
