An ophthalmic measurement device measuring optical characteristics of an anterior ocular segment of an examinee's eye comprising an optical system comprising: a laser light source irradiating the anterior ocular segment of the examinee's eye with a laser light beam from an oblique direction to the examinee's eye; a light receiving unit receiving scattered light of the laser light beam scattered at the anterior ocular segment and converting the scattered light into an electric signal; a reference light source irradiating the examinee's eye with light from a front of the examinee's eye; a photographing means photographing the examinee's eye; wherein the ophthalmic measurement device further comprises: a calculating unit calculating the optical characteristic's of the anterior ocular segment from the electric signal; a positional adjusting means adjusting relative positions of the optical system and the examinee's eye, wherein the positional adjusting means is arranged to adjust the relative positions by utilising: first reflection light generated by reflection of light emitted from the reference light source at a cornea of the examinee's eye; second reflection light generated by reflection of laser light emitted from the laser light source at the cornea of the examinee's eye; and third reflection light generated by reflection of laser light emitted from the laser light source at a crystalline lens of the examinee's eye, the ophthalmic measurement device further comprising a displaying unit for displaying an image photographed by the photographing means, wherein, in adjustment of relative positions of the optical system and the examinee's eye by the positional adjusting means, the relative positions are adjusted by approximating to respectively set target positions on the image photographed by the photographing means and displayed on the displaying unit: a position of a first bright point corresponding to a virtual image of the reference light source based on the first reflection light generated by reflection of light emitted from the reference light source at the cornea of the examinee's eye, a position of a second bright point corresponding to the second reflection light generated by reflection of laser light emitted from the laser light source at the cornea of the examinee's eye, and a position of a third bright point corresponding to the third reflection light generated by reflection of laser light emitted from the laser light source at the crystalline lens of the examinee's eye. a laser light source irradiating the anterior ocular segment of the examinee's eye with a laser light beam from an oblique direction to the examinee's eye;
