About

Tim Eixmann is a biomedical engineer whose research sits at the intersection of ophthalmic surgery, robotics, and advanced sensing. His primary contributions focus on developing and validating novel sensor technologies for vitreoretinal interventions, particularly for challenging procedures like retinal vein cannulation. Eixmann’s most cited work, a 2018 study with 41 citations, introduced a combined OCT distance and FBG force sensing cannulation needle, demonstrating its feasibility in an in vivo animal model. This innovation addresses the critical need for real-time, micron-level feedback during delicate retinal surgery. He further advanced the field with a 2021 clinical evaluation (26 citations) of an instrument-integrated OCT-based distance sensor used with the Preceyes Surgical System. This study, involving five patients, assessed the sensor’s efficacy in a robotic vitreoretinal surgery setting, marking a significant step toward safer, more precise automated procedures. By integrating optical coherence tomography directly into surgical instruments, Eixmann’s work provides surgeons with unprecedented depth perception and force feedback, directly tackling the physical limitations of human tremor and visual resolution in microsurgery. His research is foundational for the next generation of robot-assisted ophthalmic surgery.
