Abstract: A corneal preservation and rehydration device includes a box body and a box lid (1), wherein the box body and the box lid are detachably connected. A corneal bracket (2) is provided in the box body for holding a cornea, wherein a surface of the corneal bracket for placing a cornea is a convex spherical surface (21), and a blocking portion (22) is arranged at the surrounding of the convex spherical surface (21) for preventing a cornea from dropping out.

Abstract: A cornea positioning system includes: a mechanical arm assembly, an image recognition system, a background assembly arranged opposite to the image recognition system, and a calculation positioning system connected to the image recognition system. The mechanical arm assembly is configured to move a corneal package body containing a cornea to-be-positioned to be between the image recognition system and the background assembly. The background assembly is configured to provide background light. The image recognition system is configured to obtain an image formed under action of the background light of cornea packaging body. The computing positioning system is configured to analyze and calculate the image obtained by the image recognition system acquire position information about the cornea.
