A good result can be acquired with a small burden. A first target is projected on the cornea, a first target image is captured, a second target different from the first target for corneal measurement is projected on the cornea, a second target image is captured, a second amount of projection light is adjusted based on the first target image, and the cornea of the eye is measured based on the second target image. Included are a first projecting optical system (1) configured to project the first target on the cornea, a first imaging optical system (20) configured to capture a reflection image of the first target projected on the cornea, a second projecting optical system (10) configured project the second target different from the first target on the cornea to measure a corneal shape, a second imaging optical system (20) configured to capture a reflection image of the second target projected on the cornea, and a corneal shape measuring means (70) for adjusting the amount of projection light of the second projecting optical system based on the reflection image of the first target, the reflection image having been acquired by the first imaging optical system, and measuring the corneal shape of an examinee's eye based on the reflection image of the second target, the reflection image having been captured by the second imaging optical system.
