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...

The invention discloses a novel three-dimensional simulation eye which comprises a base, a simulation eye socket, an artificial cornea, an artificial iris and an artificial lens. The center of the base is provided with a semispherical eye body cavity. The outmost end of the upper surface of the base is provided with a first annular groove. The simulation eye socket is in a hollow conical shape. The outmost end of the lower surface of the base is provided with an annular convex groove which can be inserted into the first groove in the base. Three layers of insertion grooves are formed in the simulation eye socket, the lowest insertion groove is used for fixing the artificial lens, the middle insertion groove is used for fixing the artificial iris, and the uppermost insertion groove is used for fixing the artificial cornea. According to the novel three-dimensional simulation eye, the 3D printing technology is adopted, the traditional manufacturing mode of the simulation eye is simplified, the number of needed parts is small, material consumption is reduced, and the cost is reduced; rigorous optometry and ophthalmology theoretical guidance is provided, parameter selection of all the optical elements is scientific and reasonable, and feasibility and accuracy of the novel simulation eye are further proved after parameter setting and 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 ...
