目的:眼睛是人身体上最精密的器官,针对远视、近视、老花、异物侵入等不同的状况提出了很多的解决方法,表明社会上对角膜相关疾病的关注。眼科屈光手术是当今眼科医学最前沿的领域之一,激光治疗近视得到全世界的广泛应用。随着近视治疗的日臻成熟,远视治疗越来越成为人们关注的焦点。但目前针对远视,特别是高度远视的治疗还没有很好的解决方案。因此,探索激光治疗远视有着重要的学术和应用价值。方法:本文基于虚拟现实技术,构建了半导体激光角膜热成形术的医学仿真系统框架;结合面向对象设计和模块化设计方法,设计、开发了仿真系统。结果:本系统初步实现了半导体激光角膜热成形远视治疗的预测、计算和演示等仿真功能。结论:本系统的交互式仿真模块,通过预演手术的整个过程,可以使医务工作者体验和学习手术的实际操作,对改进医学教育与训练的模式、提高效率和质量,促进医学水平的提高有一定的现实意义。角膜信息数据库,能够帮助医护人员方便的进行角膜临床信息管理。随着研究的深入,在功能上可以不断完善;随着临床病例数据的增加数据库的完善预测的结果将会更加准确。系统在数据库管理模块中为数据库以及数据库中记录和属性的操作开发出完备的接口,能够方便地实现角膜数据的管理和应用。

Objective： Our eyes are one of the most complicated physical organs. Many solutions have been put forward for hyperopia, myopia, aging eye and xenembole, which shows that great attention has been paid to illnesses related with cornea. Ophthalmic refractive surgery is one of the most advanced medical fields in ophthalmology, and laser treatment of myopia has been widely used around the world. With the matured myopia treatment, the treatment of hyperopia has increasingly become the focus of attention. However, there hasn＇t been the effective treatment of hyperemia, in particular, high hyperemia. Therefore, it is both academically and practically valuable to explore the laser treatment for hyperopia. Methods： In this paper, on the basis of Virtual Reality（VR） technology, a semiconductor laser thermal angioplasty framework for medical simulation system is established. In combination with the methods of object-oriented design and modular design, a simulation system is designed and developed. Results： The system performs the initial simulation functions of forecast, calculation and demonstration of semiconductor laser corneal thermal angioplasty in the treatment for hyperopia. Conclusion： The interactive simulation of the system modules can enable medical workers to experience and learn the actual surgical operations through the rehearsal process, and can also improve the modes, efficiency and quality of medical education and training, which has its practical value for the improvement of study of medicine. Corneal information database can help medical workers to facilitate clinical cornea infor- marion management. With the deepening study, the functions can also be improved and with the increase in the data of the clinical cases and the improvement of the database, the forecast will be more accurate. The perfect interface for database,record and the property operation in the database have been developed in database management module of the system, which can easily manage and apply the corneal data.
