PROBLEM TO BE SOLVED: To accurately measure the corneal thicknesses of both the right and left eyes.SOLUTION: The corneal thickness measuring device includes: a fixation optical system that presents a fixation target to a subjects eyes from a front direction an illuminating optical system that applies illuminating light to the corneas of the subjects eyes from an oblique direction a receiving optical system having a light receiving element and receiving the illuminating light reflected from the front and back corneal surfaces of the subjects eyes and a corneal thickness calculation means for calculating the corneal thicknesses of the subjects eyes based on outputs from the light receiving element while taking a difference in the inclination of the corneas relative to the optical axis of the illuminating optical system between the right and left eyes into consideration.COPYRIGHT: (C)2012,JPO&INPIT【課題】 左右眼の角膜厚を精度良く測定できる。【解決手段】 被検者眼に対し正面方向から固視標を呈示する固視光学系と、前記被検者眼の角膜に向けて斜め方向から照明光を照射する照明光学系と、受光素子を有し、前記被検者眼の角膜表面及び裏面からの前記照明光の反射光を受光する受光光学系と、左右眼の間での前記照明光学系の光軸に対する前記角膜の傾きの違いを考慮して、前記受光素子からの出力に基づいて被検者眼の角膜厚を算出する角膜厚算出手段と、を備える。【選択図】 図4
