Robotic Microsurgery and Retinal Regeneration

Aya Barzelay-Wollman, M.D., Ph.D.
Assistant Professor
- Department of Ophthalmology
- Jules Stein Eye Institute
Dr. Aya Barzelay-Wollman leads a translational research program focused on advancing robotic-assisted microsurgery for retinal disease. Her lab develops AI-guided robotic systems capable of performing delicate intraocular surgeries with sub-millimeter precision—enabling tasks such as retinal vein cannulation, targeted subretinal delivery of gene and drug therapies, and automated intravitreal injections that exceed human manual capabilities.
Her research also explores regenerative strategies using stem cell–derived retinal grafts to replace damaged retinal tissue in degenerative diseases like age-related macular degeneration. By combining microsurgical robotics with cell-based therapies, her team aims to improve the precision, consistency, and long-term integration of these treatments, accelerating their translation into clinical care.
Dr. Barzelay-Wollman is the UCLA principal investigator for a national ARPA-H–funded initiative on whole eye transplantation. Her contributions focus on robotic microsurgery and intraocular tissue preservation, developing enabling technologies to support the viability and functional integration of transplanted eyes.

Lab Members
Graduate Students

Ting-Hao Liu(he/him)
PhD Candidate
Ting-Hao’s research focuses on sensing and control for medical robotics, image-processing algorithms, and fluidic pump control systems. His current work involves developing multimodal sensing technologies to assist surgeons in performing procedures within the confined orbital region.
Matthew Nepo
PhD Candidate
Matthew studies electromechanical properties of the eye, in the context of their use as diagnostic and surgical planning tools. His research focuses on bioimpedance for tissue diagnostics and simulation of scleral elasticity for intravitreal injection optimization.
