Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] From figure 1 It can be seen that a new type of three-dimensional simulated eye includes: a base 2 , a simulated orbit 1 , an artificial cornea 3 , an artificial iris 5 , and an artificial lens 6 . A hemispherical ocular body cavity 8 is arranged at the center of the base, and the ocular body cavity is filled with physiological saline with a refractive index of 1.3342, which is similar to that of physiological aqueous humor and vitreous body.

[0028] The base and simulated eye sockets are made by ProJET3510 HD 3D printing equipment. The outermost end of the upper surface of the base is provided with a circle of grooves 10; the outermost end of the simulated orbital lower surface is provided with a circle of convex grooves 9, and the convex grooves can be inserted into the groove 1 of the base. A groove 2 11 is arranged on the upper su...

Abstract

The invention discloses a new type of three-dimensional simulated eye, comprising: a base, a simulated orbit, an artificial cornea, an artificial iris, and an artificial lens. A hemispherical ocular body cavity is arranged in the center of the base, and a ring is arranged on the outermost end of the upper surface of the base. Groove 1; the simulated eye socket is hollow and conical, and the outermost end of the lower surface is provided with a circle of convex grooves, which can be inserted into groove 1 of the base; there are 3 layers of slots inside the simulated eye socket, and the bottom slot The intraocular lens is fixed, the middle slot fixes the artificial iris, and the uppermost slot fixes the artificial cornea. The invention adopts 3D printing technology, simplifies the traditional manufacturing mode of the simulated eye, requires fewer parts, saves consumables, and reduces costs. The invention is guided by rigorous optometry and ophthalmology theories, and the parameters of each optical element are selected scientifically and rationally. After the parameters are set, the feasibility and accuracy of the new simulated eye are further proved by optical software simulation.

Description

technical field [0001] The invention relates to a human eye model, in particular to a novel three-dimensional simulated eye. Background technique [0002] Since Gullstrand first proposed the simulated eye at the beginning of the 20th century, continuously developed and improved simulated eyes (such as Navarro, Kooijman, etc.) have come out one after another. As a tool for ophthalmology research, the simulated eye can simulate the imaging state of the eyeball under physiological or pathological conditions, so as to further explore ways to improve image quality. However, previous studies on the simulated eye were mostly limited to the theory or the simulation of related software (such as ZEMAX, MARTLAB, etc.), lacking the physical production of the simulated eye. [0003] In the past, there were only a few reports of simulated eyes produced by entities at home and abroad, such as Bakaraju simulated eyes, Arianpour simulated eyes, etc. Among them, the simulated eye entity is ...
