Research and Study on Simulation of Laser Thermo Keratoplasty / 中国医学物理学杂志

Objective: Our eyes are one of the most complicated physical organs. Many solutions have been put forward for hyperopia, myopia, aging eye and xenetnbole, 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 comeal 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 information 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 comeal data.
