Abstract:
There are various techniques available for constructing a custom ocular prosthesis. The present technique report describes a digital workflow for constructing an ocular prosthesis using computed tomography integrated with digital technologies. The outer region of the healthy eyeball was segmented to produce the top surface of the prosthesis, while the contour and bottom surface were segmented from the tissue bed of the anophthalmic socket. The iris position was determined by tracing the optical nerve and confirmed by superimposing the patient\'s facial scan onto the soft tissue model of the computed tomography. Using these parameters, a standard tessellation language file for the ocular prosthesis was generated and 3D printed. The iris was then printed via UV technology using digital photographs of the patient\'s contralateral eye; characterization of the sclera and the final layer of clear acrylic resin were done conventionally.
摘要:
存在可用于构造定制的眼部假体的各种技术。本技术报告描述了使用与数字技术集成的计算机断层摄影来构建眼假体的数字工作流程。健康眼球的外部区域被分割以产生假体的顶面,而轮廓和底面是从无眼窝的组织床中分割出来的。通过追踪视神经来确定虹膜位置,并通过将患者的面部扫描叠加到计算机断层扫描的软组织模型上来确认虹膜位置。使用这些参数,生成并3D打印了用于眼假体的标准镶嵌语言文件.然后使用患者对侧眼睛的数码照片通过UV技术打印虹膜;常规地完成巩膜和最后一层透明丙烯酸树脂的表征。本文受版权保护。保留所有权利。
