Real-time intraocular optical coherence tomography (OCT) visualization of tissues with surgical feedback can enhance retinal surgery. An intraocular 23-gauge B-mode forward-imaging co-planar OCT-forceps, coupling connectors and algorithms were developed to form a unique ophthalmic surgical robotic system. Approach to the surface of a phantom or goat retina by a manual or robotic-controlled forceps, with and without real-time OCT guidance, was performed. Efficiency of lifting phantom membranes was examined. Placing the co-planar OCT imaging probe internal to the surgical tool reduced instrument shadowing and permitted constant tracking. Robotic assistance together with real-time OCT feedback improved depth perception accuracy. The first-generation integrated OCT-forceps was capable of peeling membrane phantoms despite smooth tips.
具有手术反馈功能的实时眼内光学相干断层扫描（OCT）对组织的可视化能够提升视网膜手术效果。开发了一种眼内23号B型前向成像共面OCT镊子、耦合连接器和算法，以形成一个独特的眼科手术机器人系统。使用手动或机器人控制的镊子，在有和没有实时OCT引导的情况下，对模拟物或山羊视网膜表面进行操作。检测了提起模拟膜的效率。将共面OCT成像探头放置在手术工具内部可减少器械阴影并实现持续跟踪。机器人辅助与实时OCT反馈相结合提高了深度感知准确性。尽管第一代集成OCT镊子的尖端很光滑，但仍能够剥离模拟膜。
