This paper presents the development of a low-cost cataract surgery simulator for trainees to practise phacoemulsification procedures with computer-generated models in virtual environments. It focuses on the training of cornea incision, capsulorrhexis and phaco-sculpting, which are simulated interactively with computationally efficient algorithms developed for tissue deformation, surface cutting and volume sculpting. Intuitive two-handed human-computer interactions are achieved with six degrees-of-freedom haptic devices. Performance of trainees on manual dexterity is recorded with quantifiable metrics. The proposed virtual-reality system has the potential to serve as an alternative training tool to supplement conventional cataract surgery education.
本文介绍了一种低成本的白内障手术模拟器的开发，供学员在虚拟环境中使用计算机生成的模型练习超声乳化手术。它侧重于角膜切口、撕囊和超声雕刻的训练，这些操作通过为组织变形、表面切割和体积雕刻开发的高效计算算法进行交互式模拟。通过六自由度触觉设备实现直观的双手人机交互。用可量化的指标记录学员的手动灵活性表现。所提出的虚拟现实系统有可能作为一种替代训练工具，以补充传统的白内障手术教育。
