Abstract: The slit lamp microscope according to an exemplary embodiment comprises a scanning unit and a data processing unit. The scanning unit scans an anterior segment of an eye under examination with slit light to collect a plurality of sectional images. The data processing unit generates cloudiness distribution information which shows the distribution of clouded parts in the lens of the eye under examination on the basis of the plurality of sectional images collected by the scanning unit.

Abstract: This ophthalmic device includes an acquisition unit, an OCT unit, an analysis unit, and an estimation unit. The acquisition unit acquires the degree of refraction of a first region that includes the fovea of an eye being examined. The OCT unit acquires OCT data for the fundus of the eye using optical coherence tomography. The analysis unit identifies the shape of the fundus by analyzing the OCT data. The estimation unit estimates the degree of refraction of the region of the fundus surrounding the first region on the basis of the degree of refraction of the first region and the shape of the fundus.
