PROBLEM TO BE SOLVED: To provide an ophthalmic measurement device having a compact device configuration.SOLUTION: An ophthalmic measurement device includes: a projection optical system 20 that has a slit plate 23 provided with at least one opening formed in a radial direction for shaping a measurement light into a slit-like light, and scans an ocular fundus of a subject eye using the slit-like measurement light and a light-receiving optical system 30 that has a light-receiving unit 37 on which light receiving elements arranged in conjugation with a cornea of the subject eye, and receives the measurement light reflected at the ocular fundus using the light-receiving element. A control unit of the ophthalmic measurement device obtains refractive power of the subject eye at cornea parts in a meridian direction corresponding to the slit direction, based on a phase difference signal output from the light receiving element corresponding to each of the cornea parts. Further, the control unit drives the slit plate 23 by combining a first drive part 22a and a second drive part 23a to control scanning of the measurement light, and obtains a distribution of the refractive force of the subject eye at the cornea parts in a plurality of meridian directions.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】装置構成をコンパクトにしやすい眼科装置を提供する。【解決手段】眼科測定装置は、測定光をスリット状に整形するための開口が径方向に少なくとも1つ形成されたスリット板23を持ち、スリット状の測定光を用いて被検眼眼底を走査する投影光学系20と、被検眼角膜と共役な位置において受光素子が配置された受光ユニット37を持ち,眼底で反射される測定光を受光素子を用いて受光するための受光光学系30と、を備える。眼科測定装置の制御部は、スリット方向と対応する経線方向における角膜部位での被検眼の屈折力を、各々の角膜部位と対応する,受光素子からの位相差信号出力に基づいて得る。更に、制御部は、第1駆動部22aと、第2駆動部23aと、を組み合わせてスリット板23を駆動することによって、測定光の走査を制御し、複数の経線方向における角膜部位での被検眼の屈折力分布を得る。【選択図】図1
