A Deep Learning-Driven Autonomous System for Retinal Vein Cannulation: Validation Using a Chicken Embryo Model
Yi Wang, Peiyao Zhang, Mojtaba Esfandiari +2
Retinal vein cannulation (RVC) is a minimally invasive microsurgical procedure for treating retinal vein occlusion (RVO), a leading cause of vision impairment. However, the small s…
An Extended Generalized Prandtl-Ishlinskii Hysteresis Model for I2RIS Robot
Yiyao Yue, Mojtaba Esfandiari, Pengyuan Du +5
Retinal surgery requires extreme precision due to constrained anatomical spaces in the human retina. To assist surgeons achieve this level of accuracy, the Improved Integrated Robo…
Model Predictive Path Integral Control of I2RIS Robot Using RBF Identifier and Extended Kalman Filter
Mojtaba Esfandiari, Pengyuan Du, Haochen Wei +4
Modeling and controlling cable-driven snake robots is a challenging problem due to nonlinear mechanical properties such as hysteresis, variable stiffness, and unknown friction betw…
Towards Motion Compensation in Autonomous Robotic Subretinal Injections
Demir Arikan, Peiyao Zhang, Michael Sommersperger +7
Exudative (wet) age-related macular degeneration (AMD) is a leading cause of vision loss in older adults, typically treated with intravitreal injections. Emerging therapies, such a…
Real-time Deformation-aware Control for Autonomous Robotic Subretinal Injection under iOCT Guidance
Demir Arikan, Peiyao Zhang, Michael Sommersperger +7
Robotic platforms provide consistent and precise tool positioning that significantly enhances retinal microsurgery. Integrating such systems with intraoperative optical coherence t…
