PROBLEM TO BE SOLVED: To provide an anterior eye part optical interference tomographic device capable of measuring an accurate corneal shape by avoiding overlap of an image of eyelashes or a pupil in a folding image with a corneal part in an anterior eye part tomogram.SOLUTION: A zero point position of an interference optical system is set between the center of a crystalline lens and a rear surface of the crystalline lens. Hereby, since a folding image of an anterior eye part tomogram is folded from a furthermore rear side than the crystalline lens and overlapped with a normal image, overlap of an image of eyelashes or a pupil in the folding image with a corneal part of an anterior eye part tomogram can be avoided, to thereby enable accurate measurement of a corneal shape.SELECTED DRAWING: Figure 8 |
