摘要： An ophthalmic device is provided with: a first scanning optical system configured to scan first light outputted from a first light source in a first range of a subject eye; and a second scanning optical system configured to scan a second light outputted from a second light source in a second range of the subject eye that is different from the first range. A central wavelength of the first light and a central wavelength of the second light are different. The first scanning optical system includes a first objective lens unit configured to irradiate the first light to the first range of the subject eye. The second scanning optical system includes a second objective lens unit configured to irradiate the second light to the second range of the subject eye.

摘要： An anterior eye tomographic image capturing apparatus determining a power of an IOL (intraocular lens) is configured to acquire a tomographic image of an anterior eye along a straight line passing through a corneal apex of the anterior eye; identify a corneal apex position of the anterior eye, an equator position of a crystalline lens of the anterior eye, and a SS (scleral spur) position of the anterior eye based on the tomographic image; calculate an ELP (estimated lens position) based on a first distance from the corneal apex position to the SS position in a direction of a visual axis and a second distance from the SS position to the equator position in the direction of the visual axis; and determine the power of the IOL by using the ELP.

摘要： An eye refractive power measuring apparatus includes a light projecting optical system, a light receiving optical system, a focusing unit, a calibration optical system, a focus control unit, and an arithmetic unit. The arithmetic unit, based on a relation of a control signal obtained when a calibration beam is projected and a calibration value that is an output of a light receiving unit, and a correlation of a calibration value obtained in advance and eye refractive power, calculates a correlation of the control signal and the eye refractive power, and, based on a control signal obtained when measuring beam is projected, a measured value that is an output of the light receiving unit, and the correlation, calculates the eye refractive power.

摘要： An ophthalmic apparatus that includes an image capturing unit configured to capture a target part of a subject eye; a processor; and a memory storing computer-readable instructions therein. The computer-readable instructions, when executed by the processor, may cause the ophthalmic apparatus to execute: acquiring a first image of the target part captured at a first timing by the image capturing unit and a second image of the target part captured at a second timing different from the first timing; and combining the first image with the second image to generate one combined image of the target part.
