背景随着激光辅助平台的发展，几种手术的自动化已经改善了白内障手术的结果。白内障摘除步骤仍然是手动进行的，但由于感知能力的不足，后囊破裂和不完全白内障摘除等手术并发症仍然存在。方法将光学相干断层成像(OCT)系统集成到我们的眼内机器人介入手术系统(IRIS)中。OCT图像用于一系列自动化程序的术前计划和术中干预。实时干预使外科医生能够评估进展并取消手术。结果通过对30只死后猪眼进行晶状体摘除实验，验证了该系统的有效性。25只眼完成了晶状体摘除，其余的由于无法成像虹膜后的小晶状体颗粒而实现了“几乎完全”的摘除。未发现包膜破裂。结论在实时监测和干预下，IRIS成功地实现了OCT引导下的半自动晶状体摘除。
Background With the development of laser-assisted platforms, the outcomes of cataract surgery have been improved by automating several procedures. The cataract-extraction step continues to be manually performed, but due to deficiencies in sensing capabilities, surgical complications such as posterior capsule rupture and incomplete cataract removal remain. Methods An optical coherence tomography (OCT) system is integrated into our intraocular robotic interventional surgical system (IRISS) robot. The OCT images are used for preoperative planning and intraoperative intervention in a series of automated procedures. Real-time intervention allows surgeons to evaluate the progress and override the operation. Results The developed system was validated by performing lens extraction on 30 postmortem pig eyes. Complete lens extraction was achieved on 25 eyes, and "almost complete" extraction was achieved on the remainder due to an inability to image small lens particles behind the iris. No capsule rupture was found. Conclusion The IRISS successfully demonstrated semiautomated OCT-guided lens removal with real-time supervision and intervention.
