A groundbreaking project aiming to bring eye transplants into the realm of reality has received a major boost with a $47 million award from ARPA-H. This six-year initiative, known as THEA (Total Human Eye-allotransplantation Innovation Advancement), seeks to advance eye transplantation technology to the point of clinical trials.
While a single whole-eye transplant has been successfully performed as part of a face transplant in 2023, the transplanted eye did not restore vision. The THEA project aims to overcome this hurdle by tackling several key challenges, including preserving donated eyes, repairing the optic nerve, and establishing comprehensive protocols for the entire transplantation process.
Eight leading organizations, including the USC Roski Eye Institute, are collaborating on THEA.This interdisciplinary team, spearheaded by dr.Kia Washington at the University of Colorado Anschutz Medical Campus, brings together expertise from Cedars-Sinai Medical Center, the Foundation Fighting Blindness, Indiana University, Johns Hopkins University, the National Eye Institute, and the University of Wisconsin–Madison.
Dr. Kimberly gokoffski, a neuro-ophthalmologist and surgeon-scientist at the Keck School of Medicine, leads USCS contribution to the project.She emphasizes the transformative potential of this research: “Until ARPA-H created the prospect, the concept of eye transplantation felt too sci-fi, too out of reach, for many,” Dr. Gokoffski stated. “Though, as of recent medical and scientific advancements, a lot of us began to realize that this was something worth pursuing.”
Dr.Gokoffski’s team at USC is focusing on two critical areas: developing a system to stimulate nerve growth through electrical impulses, and creating protocols for donor and patient selection, surgical procedures, and post-operative care.
“There’s a lot of work to be done, for instance, optimizing the balance of what you preserve in the patient and what you harvest from the donor,” Dr. Gokoffski explains.
The USC team comprises specialists from USC and the University of California, Irvine, representing diverse fields including ophthalmology, neurosurgery, neurobiology, and bioengineering. Notable members include Dr. Gianluca Lazzi, the director of the USC Institute for Technology and Medical Systems, Dr. Mark Humayun, the inventor of an FDA-approved “bionic eye” device, and Dr. Arthur Toga, a world-renowned brain imaging expert.
“engineers and biologists and clinicians all think differently, and we’re understanding the importance of convergent research linking different schools of thought. Interdisciplinarity is a strength at USC, and something we hope to capitalize on. We also have a tradition of success and excellence – researchers with experience taking a technology literally from concept to”
Revolutionary Eye Transplant Research Aims to Restore Sight
Leading neuro-ophthalmologist Kimberly Gokoffski, MD, PhD, has received a substantial grant to advance groundbreaking eye transplant research aimed at restoring sight in patients with severe vision loss. The enterprising project, supported by the Advanced Research Projects Agency for Health (ARPA-H), leverages a collaborative approach, bringing together experts from diverse fields and institutions. Dr. Gokoffski’s team at the USC Roski Eye Institute will combine their expertise with cutting-edge technologies to address the complex challenges of eye transplantation. Utilizing a series of implanted devices in the eye and brain, the research will focus on stimulating nerve growth and minimizing inflammation.Harnessing the Power of Electrical Stimulation
A key component of this innovative approach involves using electrical stimulation to guide nerve regeneration. “If you only drive growth of neurons from within, it’s kind of like hitting the gas without controlling the steering,” Gokoffski explained. “The electric fields do provide gas, but they primarily provide the steering cue. Our research essentially aims to use natural cellular responses to electric fields to guide the nerves to grow to where they need to grow. If we rewire improperly, patients could experience visual confusion.” This strategy will involve strategically placed devices, including a cuff around the junction of donated and host tissue, to deliver both electrical stimulation and biologic treatments.A Collaborative Effort for Vision Restoration
Recognizing the multifaceted nature of this project, Dr.Gokoffski has established collaborations with leading institutions and companies. She is working closely with Dr. darrin Lee, MD, PhD, a neurosurgeon at USC, Dr. Kia Washington and other plastic surgeons from CU anschutz, and transplant surgeons from Cedars-Sinai. The USC Roski Eye Institute will recruit and enroll eligible patients for this pioneering clinical trial. Following transplantation and postoperative care at Cedars-Sinai, patients will undergo follow-up assessments at the USC Roski Eye Institute. Further partnerships are anticipated, including philanthropic organizations committed to restoring sight and investors interested in advancing the component technologies involved. “To achieve the biggest goals, we really need to join together and pool our resources,” Gokoffski emphasized. “Bringing people together to achieve a big goal is exactly what ARPA-H is trying to do.”## Archyde Interview:
**Archyde:**
Dr.Gokoffski, thank you for joining us today. The news of this $47 million grant from ARPA-H for eye transplant research has generated a lot of excitement. Can you tell our readers a little about THEA and what this funding will allow you to achieve?
**Dr. Kimberly Gokoffski:**
It’s a pleasure to be hear. You’re right, the announcement has been met with considerable enthusiasm. THEA,or Total Human Eye-allotransplantation Innovation Advancement,represents a game-changing prospect to move eye transplantation from the realm of science fiction to clinical reality.
This six-year initiative will bring together leading experts from eight institutions across the country, including the USC Roski Eye Institute, under the leadership of Dr. Kia washington at the University of Colorado Anschutz Medical Campus.
The injection of this substantial funding will allow us to tackle some of the biggest hurdles in eye transplantation, such as preserving donated eyes, repairing the complex optic nerve, and developing rigorous protocols for the entire transplantation process.
**Archyde:** As you mentioned, a single whole-eye transplant was performed in 2023 as part of a face transplant, but vision wasn’t restored. How will THEA aim to overcome this challenge?
**Dr. Gokoffski:**
That’s correct. While that initial success was a landmark achievement, it highlighted the complexities we still need to address. At USC, we’re focusing on two critical areas.First, we’re exploring innovative methods to stimulate nerve growth within the optic nerve using electrical impulses.
Second, we’re developing detailed protocols for donor and patient selection, surgical procedures, and post-operative care. As an example, we’re looking at optimizing the balance between what we preserve in the patient and what we harvest from the donor to maximize the chances of prosperous transplantation.
**Archyde:**
It sounds like a truly interdisciplinary effort.
**Dr. Gokoffski:**
Absolutely. [1] We have a phenomenal team at USC, including experts from the Keck School of Medicine, the University of California, Irvine, and the USC Institute for Technology and Medical Systems.
Our team draws on expertise from ophthalmology, neurosurgery, neurobiology, bioengineering, and even brain imaging. We have specialists like Dr. Gianluca lazzi, Dr. Mark Humayun, who invented an FDA-approved “bionic eye” device, and Dr. Arthur Toga, a world-renowned brain imaging expert, all contributing their unique perspectives.

This interdisciplinary approach is essential because engineers, biologists, and clinicians all think differently. We’re learning the power of convergent research, where different schools of thought come together to find creative solutions to complex problems.
**Archyde:**
What does the future hold for eye transplantation research? When can we realistically expect to see these treatments available to patients in need?
**Dr. Gokoffski:**
It’s hard to predict a precise timeline, but this grant brings us significantly closer to that goal. Our focus is on laying the groundwork for clinical trials within the next six years.
Success in these trials would pave the way for wider adoption of eye transplantation, perhaps changing the lives of countless individuals with vision loss. The potential for this research is truly transformative, and I’m incredibly excited to be a part of it.
