一个伦敦男人有据说成为世界上第一个配备3D印刷假肢的人。
史蒂夫·韦尔兹（Steve Verze）今天在Moorfields眼科医院在伦敦的芬斯伯里（Finsbury），它比传统的丙烯酸假肢提供了更现实的外观，并且可以在短时间内制造。
Professor Mandeep Sagoo, Consultant Ophthalmologist at Moorfields Eye Hospital, hopes the forthcoming clinical trial of the 3D printed prosthetic eye will provide the team with “robust evidence” of the value of the technology, and says it has the potential to reduce waiting lists.
Optical 3D printing
Moorfields眼科医院is claiming the delivery of the 3D printed prosthetic eye as a world first, and while this does appear to be the case there has been some previous research in the area of optical prosthetics and grafts.
设计机构Fripp设计has been developing 3D printed artificial eyes for a number of years in partnership with曼彻斯特大都会大学和谢菲尔德大学。过去，公司有claimed to be able to produce over 120 eyes in an hour具有专利的过程。
However, last year owner Steve Roberts announced his intention to出售公司的3D打印硅胶IP为了追求其他野心。3D印刷眼肢假肢的发展是否仍在继续尚待观察。
2018年，遣散医院Yonsei University Health System（Yuhs）宣布了计划商业化其第一个3D印刷人造眼，作为由韩国科学和ICT。原型预定到2020年准备就绪，但是医院尚未提供有关其进度的最新消息。
在其他地方，以前已经部署了3D打印来提供帮助重建眼睛of a 47-year-old woman. The woman’s face was captured using 3D scanning and CAD modeling techniques to give a customized eye model which was then 3D printed via SLA to form a mold to make the artificial eye.
虽然完全3D印刷眼睛的假肢可能是人类的第一个，但人的最好的朋友已经从技术中受益。去年，来自Chungbuk National University发达low-cost personalized artificial eyes for canines那已经失去了无法治愈的疾病。3D印刷假肢在两个小猎犬上成功测试，并被认为在兽医应用中具有“巨大潜力”。
3D打印的假肢
今天，似乎是第一次清除了3D打印的假肢，以作为临床试验的一部分进行人类使用。
目前，装有传统的丙烯酸人造眼是一个漫长而又引人入胜的过程，患者必须进行两个小时的疗程以塑造其眼窝，然后再安装原状然后进行涂漆。总共，这个过程可能需要大约六个星期。
根据Moorfields的说法，3D打印提供了更快的替代方案，将制造过程减少到仅两到三周。测量眼窝的最初预约也缩短到仅半小时。
Ocupeye andFraunhofer IGDlent their software expertise to the project, which is supported by the国家健康研究所， 这Moorfields生物医学研究中心, andMoorfields Eye Charity。Once Verze’s eye socket had been scanned and the data modeled, the customized eye prosthetic was printed by German 3D printing service bureauFIT AG。
The hospital also believes the 3D printed prosthetic eye is more realistic looking than a traditional acrylic one, due to the way light is able to travel through the full depth of the printed eye. This sentiment is echoed by Verze, who has always “felt self-conscious” about his artificial prosthetic.
他说：“这种新的眼睛看起来很棒，并且基于3D数字印刷技术，它只会变得越来越好。”
Sagoo and his team at Moorfields Eye Hospital are optimistic about the forthcoming clinical trial, and believe the technology has the potential to significantly reduce waiting lists for patients needing eye prosthetics.
