Abstract: An observation device includes: a holding board that holds an observation container accommodating a cornea for transplantation to be observed; a specular reflection optical system including an illumination optical system and an imaging optical system, which include a light source and an imaging unit, for observing the cornea for transplantation; and an auxiliary light source that illuminates the cornea for transplantation from the back and has an auxiliary illumination optical axis inclined with respect to an observation base axis that divides in half an intersecting angle of the illumination optical axis of the illumination optical system and an imaging optical axis of the imaging optical system, wherein the auxiliary light source is installed in a freely pivoting manner about a predetermined rotation axis so that a relative inclination angle with respect to the observation base axis of the auxiliary illumination optical axis can be continuously changed.

Abstract: The present invention is directed to a system for observing a cornea for transplantation which includes: an illumination means for illuminating the cornea for transplantation contained in a container; an entire-view imaging means for imaging the substantial entirety of the interior of the container; a position adjusting means for adjusting the position and angle of the cornea for transplantation; a magnified-view imaging means for imaging a magnified view of the cornea for transplantation illuminated by the illumination means; an image display means for displaying each image taken by the entire-view imaging means and the magnified-view imaging means; and an image control means for controlling each image.

Abstract: A corneal endothelium analysis service method which provides an analysis service of corneal endothelium image data to a client through a network, includes a receiving step for receiving the corneal endothelium image data which is transmitted from a terminal owned by a client. The received corneal endothelium image data is analyzed and the analysis result is transmitted to the client terminal.
