在白内障手术中,抛光后囊(PC)可以改善手术结果,但由于其高风险性,目前被避免。这项工作开发了一个机器人系统,能够执行PC抛光离体猪眼使用光学相干断层扫描(OCT)的指导。取出5只离体猪眼的晶状体,并在PC上沉积一薄层胶水。使用眼前节的经瞳孔OCT扫描生成PC抛光轨迹。在抛光过程中,OCT B扫描跟踪刀头并显示给操作员。在所有5次试验中均完成了胶水的完全清除,未报告PC破裂。证明了使用由OCT引导的机器人系统在生物模型上进行PC抛光的可行性。贡献包括PC解剖结构的建模、术中OCT可视化和具有预定抽吸压力的自动工具尖端运动。
In cataract surgery, polishing of the posterior capsule (PC) can lead to improved surgical outcomes but is currently avoided due to its high-risk nature. This work developed a robotic system capable of performing PC polishing on ex vivo pig eyes using optical coherence tomography (OCT) guidance. The lenses of five ex vivo pig eyes were extracted and a thin layer of glue deposited onto the PC. Transpupillary OCT scans of the anterior segment were used to generate a PC-polishing trajectory. During polishing, OCT B-scans tracked the tool tip and were displayed to the operator. Complete removal of the glue was accomplished in all five trials with no PC rupture reported. The feasibility of using a robotic system guided by OCT to perform PC polishing on a biological model was demonstrated. Contributions include modelling of the PC anatomy, intraoperative OCT visualization, and automated tool-tip motion with scheduled aspiration pressures.
