摘要

为了对圆锥角膜为代表的角膜扩张类疾病进行安全有效的治疗，减小手术过程中的人工对准误差，设计了一种用于角膜交联手术装置的光学系统。根据角膜交联手术治疗光斑尺寸、均匀性及工作距的要求，基于复眼透镜阵列匀光原理进行了照明系统设计。设计了一种对人眼区域成像，工作距离为175 mm，放大率

=-4.2的红外镜头。最后，搭建了角膜交联装置原理样机，并对所设计的光学系统进行了测试。实验结果表明，紫外照明光路工作距离为65 mm，输出光斑直径为9 mm，均匀度为90.2%，达到了国外同类仪器水平，红外成像光路可以为手术过程中人眼位置的追踪和定位提供清晰、良好的图像。本文设计的角膜交联装置的光学系统具有结构简单、成本低廉、性能良好等特点，可以很好地满足手术需要。

Abstract

To treat corneal dilatation diseases caused by keratoconus safely and effectively and to reduce manual alignment errors during surgery

an optical system for a corneal cross-linking surgical device was designed in this study. First

based on the requirements of corneal cross-linking surgery related to spot size

uniformity

and working distance

an illumination system was designed based on the principle of uniformation of the compound eye lens array. Second

an infrared lens was designed that was imaged by the human eye with a working distance of 175 mm and a magnification

of -4.2. The aforementioned design was then processed

a prototype of the corneal cross-linking device was built

and the designed optical system was tested experimentally. Experimental results show that the UV illumination light path is 65 mm

output spot diameter is 9 mm

and uniformity is 90.2%

which are comparable to those of similar instruments abroad. The infrared imaging light path can provide clear and quality images for tracking and positioning the human eye during a surgical operation. The optical system of the corneal cross-linking device designed in this study has the characteristics of a simple structure; further

it is low cost

exhibits good performance

and can well meet surgical requirements.
