[0033] As an alternative implementation, the lens assembly further includes a corneal refractive state simulation lens group after corneal reshaping by orthokeratology lenses.

Preferably, the corneal refractive state simulation lens after corneal reshaping by orthokeratology lenses is detachably mounted on the third rod holder so as to replace and mount different types of corneal refractive state simulation lenses after corneal reshaping by orthokeratology lenses, and realize the test and display of multiple types of lenses. As a feasible implementation method, a second lens card slot is provided on the front side of the top of the third rod holder, and the corneal refractive state simulation lens after corneal reshaping by orthokeratology lenses is detachably mounted in the second lens card slot. A light transmission hole structure 11 is provided on the rear side of the top of the third rod holder.

[0037] In an ophthalmic medical education display model device of the present application, the refractive lens and the corneal refractive state simulation lens after orthokeratology in the lens assembly can be applied separately or in combination; that is, the imaging light source beam emitted by the laser lamp passes through the refractive lens or the corneal refractive state simulation lens after orthokeratology and is projected onto the imaging board for imaging; it is also possible that the imaging light source beam emitted by the laser lamp passes through the refractive lens and then passes through the corneal refractive state simulation lens after orthokeratology and is projected onto the imaging board for imaging. By sliding and adjusting the distance between the imaging board and the lens assembly, clear imaging of lenses with different parameters on the imaging board can be achieved. The distances required for clear imaging of myopic lenses and hyperopic lenses in the optical refractive lenses on the imaging board are different. By sliding the fourth rod holder to drive the imaging board to move, the corresponding imaging distance requirements can be met; the distances required for clear imaging of the corneal refractive state simulation lenses after orthokeratology with different parameters on the imaging board are also different. By sliding the fourth rod holder to drive the imaging board to move, the corresponding imaging distance requirements can also be met.

An imaging effect of the imaging board group in the actual application of the device of the present application: A first corneal refractive state simulation lens after orthokeratology is pre-installed on the third rod holder. After the imaging light source beam passes through the first corneal refractive state simulation lens after orthokeratology, it is projected onto the imaging board, and clear imaging is just achieved on the large imaging board formed by splicing the three imaging panels on the left, middle, and right with the distance adjusted; then, after removing the first corneal refractive state simulation lens after orthokeratology and replacing it with the second corneal refractive state simulation lens after orthokeratology, the imaging of the two imaging panels on the left and right in the overall large imaging board is not clear, and the middle imaging panel is clearly imaged. At this time, by pushing the two imaging panels on the left and right forward or backward, that is, by re-adjusting the distance between the two imaging panels on the left and right and the corneal refractive state simulation lens after orthokeratology, the light source beam emitted by the laser lamp can also be clearly imaged in the two imaging panels on the left and right; through the display of the imaging results in the imaging panel, the myopia and hyperopia defocus principles in eye vision can be intuitively and effectively explained.
