Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an eye teaching aid model for displaying cornea in layers. Background Art

[0002] The eye model is a schematic model made according to the structure of the human eyeball. The current ophthalmic models are mainly used to explain the surgical plan to the patients and describe to the patients what kind of operation will be performed on which part of the eye. After searching, the Chinese patent authorization number CN207264657U discloses a human eye anatomical model. By adding corresponding LED lights to the eye model, the model can clearly display the eye structure under darker conditions. It is more intuitive and easier to explain and operate than ordinary eye models. However, the current eyeball model does not design the five-layer structure of the cornea separately, and designs the cornea as an integral structure, which is not convenient for explaining the surgical process to the patients. In addition, for surgeries that require lens implantation, it is not convenient to use existing models to explain the lens implantation process. Utility Model Content
