Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with specific examples. The following examples are explanations of the present invention, and the present invention is not limited to the following examples.

[0030] A kind of artificial cornea, its preparation method is as follows:

[0031] (1) Establish the human eye vision model. Scan the 3D data of a statistical number of human eyeballs, and through statistical analysis, finally obtain the human eye vision model;

[0032] (2) 3D scanning to establish the patient's personal eyeball model On the basis of the above-mentioned human eye visual model, 3D scanning is performed on the patient's eyeball through a 3D data scanner or other medical measuring instruments to obtain the patient's personal eyeball model data. The 3D data here includes the patient's eyeball model. Curvature, diopter and other data of the affected eye, which can be obtained by OCT, CT, nuclear magnetic resonance and other...

Abstract

The invention discloses artificial cornea and a manufacturing method thereof and relates to the technical field of artificial organs. The artificial cornea is manufactured based on 3D (three dimensional) printing technology. The manufacturing method includes setting up a human vision model; setting up a personal eyeball model by 3D scanning; importing data into a 3D printer; preparing printing materials; scanning the printing materials point by point through ultraviolet laser beams with wave length in 355 nm and beam quality M2 in 1.0-1.3, curing the liquid-state printing materials from point to line and line to surface, controlling a lifting platform to move by a computer, curing the liquid-state printing materials layer by layer, and finally stacking layer by layer to obtain a 3D-printed cured product; freezing and forming and successively processing. The manufacturing method is quick and accurate, simple and feasible to operate, low in cost, and capable of accurately controlling the microstructure of the materials. The artificial cornea is perfectly matched with an original optometric system of a patient, and the requirements of different patients for individual diopter can be met.

Description

technical field [0001] The invention relates to the technical field of artificial organs, in particular to an artificial cornea prepared based on 3D printing technology and a preparation method thereof. Background technique [0002] The blindness of more than 10 million people in the world is caused by corneal disease, which is the second leading cause of blindness after cataract. Among them, 80% can be relieved of blindness through corneal transplantation. However, traditional corneal transplantation has two major disadvantages. One is the difficulty in obtaining corneal donors, and the other is the low success rate of the operation. The emergence and application of artificial corneas have brought hope to patients with corneal blindness. [0003] The artificial cornea is a product similar to the human cornea made of medical polymer materials. The artificial cornea generally includes two parts: an optical lens column and a peripheral bracket. The optical mirror column is ...
