<P>PROBLEM TO BE SOLVED: To acquire an accurate measurement result without applying a high load on an examinee. <P>SOLUTION: A corneal shape measurement instrument includes: a first projection optical system (1) for projecting a first index to a corneal; a first imaging optical system (20) for imaging the reflection image of the first index projected on the corneal; a second projection optical system (10) for projecting a second index different from the first index to the corneal in order to measure a corneal shape; a second imaging optical system (20) for imaging the reflection image of the second index projected to the corneal; and a corneal shape measurement means (70) for adjusting the amount of projection light of the second projection optical system, based on the reflection image of the first index which is acquired by the first imaging optical system, and measuring the corneal shape of the eye of the examinee, based on the reflection image of the second index which is imaged by the second imaging optical system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
