This Q&A is part of a series highlighting the breadth of research across UCSF Ophthalmology. In this installment, Tyson Kim, MD, PhD, discusses how he leverages his engineering background to develop new technologies with the goal of curing forms of blindness in his career.

 

Q: What drew you to medicine and ultimately to ophthalmology?

A: I started out deeply interested in physics and engineering. But during college, I had a medical emergency and associated bills which prompted me to nearly drop out. My surgeon stepped in and alleviated the costs so I could stay in school.

That experience fundamentally changed my trajectory, sparking a commitment to the humanitarian side of medicine.

It also took time to figure out how to combine engineering with medicine. I found that ophthalmology was the perfect intersection. There’s a strong foundation in optics and technology, and it’s one of the fastest fields for translating innovation into patient care. Restoring vision can have an immediate, life-changing impact.

 

Q: How does your background in engineering shape your research today?

A: My lab focuses on developing new optical imaging and laser technologies to better understand and treat eye disease. I started by building advanced microscopes during my PhD, and that work has evolved into a full-scale optics lab where we design both imaging systems and therapeutic platforms.

We’re not just observing disease, we’re creating entirely new ways to visualize and intervene, often at the cellular level, in living systems. That combination of physics, engineering and medicine is what drives our work.

 

Q: Can you describe one of your most promising innovations?

A: One major focus is glaucoma, a leading cause of irreversible blindness. All currently approved treatments aim to lower pressure inside the eye, but they can be invasive or ineffective for some patients.

We’ve developed a technology that allows us to see deep in the eye, even through non-transparent tissues, at cellular resolution. For the first time, we can directly and non-invasively visualize and measure how fluid flows through the eye’s drainage system.

What’s especially exciting is that we can then use this platform to deliver targeted laser therapy without incisions or invasive surgery. It’s essentially non-invasive, image-guided laser surgery. If successful in clinical trials, this could fundamentally change how we treat glaucoma.

 

Q: How do you move technologies like this from the lab to patients?

A: We pursue both academic and translational pathways. On one side, we conduct NIH-funded research and publish discoveries. On the other, we patent our technologies and launch spinout companies to bring them into clinical use.

The goal is always the same: to move innovations as quickly and safely as possible from the lab bench to patient care.

 

Q: Your work also contributed to a discovery about retinal neurons and blood vessels. What was significant about that?

A: That discovery came from combining advanced imaging with biological expertise. Our tools allow us to observe the living eye in 3D over time, capturing interactions between neurons and blood vessels with unprecedented detail.

In collaboration with Xin Duan, PhD, we used this capability to identify a previously unknown mechanism of neurovascular development. It’s a great example of how new tools enable collaboration and can unlock entirely new biology.

 

Q: There’s growing interest in the idea of the eye as a “window to the body.” What does that mean?

A: The eye is unique because it’s the only place in the body where we can directly visualize blood vessels and neural tissue non-invasively and with microscopic resolution. Historically, clinicians have used this qualitatively, for example, noticing signs of high blood pressure or diabetes.

Now, with advanced imaging and AI, we can quantify these signals. That means we can potentially detect or predict systemic diseases—like heart disease or stroke—just from an image of the eye.

This is part of a broader field called “oculomics,” where we use the eye as a platform for understanding whole-body health.

 

Q: What excites you most about the future of this work?

A: The combination of accessibility and precision. The eye is one of the best places in the body to both study disease and test new therapies. It’s often where major medical breakthroughs happen first including gene therapy, stem cell therapy, targeted biologics, and artificial intelligence.

Now, with advances in imaging, laser technology, and computation, we’re entering a phase where we can not only see disease in unprecedented detail, but also intervene with incredible precision.

 

Q: Why is UCSF and the Bay Area an ideal place for this research?

A: UCSF provides an outstanding clinical and research environment, with strong institutional support and a top-tier ophthalmology program.

Equally important is the Bay Area ecosystem. The culture of innovation, entrepreneurship, and collaboration makes it possible to rapidly translate ideas into real-world solutions. That combination accelerates progress in a way that’s hard to replicate elsewhere.

 

Q: What impact do you hope your work will have?

A: If I can help cure even one or two forms of blindness in my career, that would be incredibly meaningful. And right now, it feels like that’s within reach.

Dr. Nisha Acharya is a world-renowned clinician-scientist with over two decades of experience as both a practicing ophthalmologist and a leader of a continuously NIH-funded research program focused on clinical trials and large-scale data analysis. She has been the PI, co-PI, or protocol chair of several NIH-funded large multicenter clinical trials, as well as big data projects. Her work has been grounded in addressing clinically meaningful questions related to ocular infectious and inflammatory conditions and translating evidence into clinical practice.

In her early career, under the mentorship of Dr. Tom Lietman of UCSF, she helped implement the Steroids for Corneal Ulcer Trial (SCUT) and the Mycotic Ulcer Treatment Trial (MUTT). These trials focused on the optimal treatment for bacterial and fungal corneal ulcers. She then established a research program focusing on uveitis, a group of conditions characterized by intraocular inflammation. She led the First-line Antimetabolites as Steroid-sparing Treatment (FAST) Trial, published in JAMA in 2019, which demonstrated that a widely available, inexpensive immunosuppressive drug is comparable to a more expensive drug for the treatment of uveitis, challenging long-standing assumptions in the field and shifting practice patterns worldwide. Dr. Acharya led the Adalimumab in Juvenile Idiopathic Arthritis-associated Uveitis Stopping Trial (ADJUST), published in The Lancet in 2025. This trial studied the discontinuation of adalimumab in children with juvenile idiopathic arthritis-associated uveitis and demonstrated that 75% of children relapsed after stopping treatment, challenging current guidelines on treatment discontinuation and providing clinically relevant information for treating physicians and families on the implications of treatment withdrawal.

In addition to her clinical trials, Dr. Acharya has conducted groundbreaking epidemiologic studies using large data sources. She has had an R01 grant since 2018 to study the impact of the herpes zoster vaccine on herpes zoster and herpes zoster ophthalmicus and has published studies assessing the effectiveness of the recombinant zoster vaccination for preventing herpes zoster and dementia. Her work has highlighted the need for greater public health efforts to identify and address potential barriers to herpes zoster vaccination. During the COVID pandemic, she reported on risks of hospitalization and death in patients taking immunosuppression for ocular inflammatory diseases, and she studied the impact of COVID vaccines on ocular inflammation.

Dr. Nisha Acharya is the Elizabeth C. Proctor Distinguished Professor at the F.I. Proctor Foundation and Departments of Ophthalmology and Epidemiology and Biostatistics, and she is the Director of the Uveitis and Ocular Inflammatory Disease Service. She is Vice Chair for Faculty Development and Mentorship in the Department of Ophthalmology. She has mentored many students, residents, fellows, and faculty, and was awarded a Dean’s Award for Research Mentorship of medical students in 2020, 2024, and 2025. She has served in many leadership roles, including President of the American Uveitis Society. She was awarded the 2026 Mildred Weisenfeld Award for Excellence in Ophthalmology by the Association for Research in Vision and Ophthalmology, which is presented to an individual in recognition of distinguished scholarly contributions to the clinical practice of ophthalmology.

Retinal Regeneration

AUDACIOUS GOALS

What if individuals disabled by retinal vision loss could embark on a journey aboard a rocket that would restore their sight?

The Audacious Goals Initiative, established by the National Eye Institute in 2018, has made it a primary objective to conduct research aimed at creating such a groundbreaking “rocket” within the next 10 to 15 years by restoring vision through regeneration of the retina. Distinguished scientists from across the nation are joining forces, collaborating to push the boundaries of vision science.

With gifts over $2 million thus far, a team of four vision scientists from UCSF are co-leading five-year cross-disciplinary investigations to advance this federal initiative.

Their triumph, along with the success of the entire initiative, holds the potential to revolutionize treatment and outcomes for individuals diagnosed with macular degeneration, glaucoma, inherited retinal disorders, retinal detachments, and traumatic retinal injuries.
 

Developing new imaging tools

One of the multi-site teams, led by UCSF Ophthalmology Chair, Jacque Duncan, MD, in partnership with Jay Stewart, MD and Deepak Lamba, MBBS, PhD, is diligently working on developing new imaging tools capable of scrutinizing the eye with unparalleled precision. Collaborating with Austin Roorda, PhD (UC Berkeley), and Joseph Carroll, PhD (Medical College of Wisconsin), Dr. Duncan utilizes these advanced tools to record light-sensing cells in patients with healthy retinas. Then they compare the healthy retinas to retinas of those with degenerating cells caused by genetic mutations and patients with retinal detachment after surgical repair.

Stem cell biologist Deepak Lamba, MBBS, PhD, and his team are actively engaged in creating research models that increasingly emulate macular characteristics and diseases. Dr. Duncan compares the structure and function of these experimental photoreceptor cells to the images of cells from her patients diagnosed with macular diseases and inherited retinal degeneration. The closer the resemblance between the two, the higher the credibility of the lab-generated model.

Additionally, Dr. Lamba collaborates with Dr. Carroll to evaluate the potential of these cells to integrate into a diseased retina for visual recovery.

studied image-transmitting cells in the retina, Dr. Ou’s lab then reconstructs the anatomic circuitry of the transplanted cells to determine to what extent they have integrated within the retina affected by glaucoma.
 

Collaboration works

In addition to funding, the Audacious Goals Initiative fosters regular collaboration among all the research teams, enabling feedback, information sharing, and input from an advisory group. This collaborative approach has already proven fruitful. As Dr. Duncan states, “With this support, we can fine-tune our approaches mid-course, accelerating discovery. It’s unlike any other federal grant I’ve been awarded.”

This past spring, a remarkable breakthrough in cataract technology brought renewed hope to patients seeking improved vision. All May See’s President Emerita, Kathleen Rydar, underwent cataract surgery at UCSF, where Associate Professor Julie Schallhorn, MD, MS, performed the procedure using an innovative Light Adjustable Lens™ (LAL). These groundbreaking lenses, developed by UCSF’s very own Daniel Schwartz, MD, in collaboration with Nobel Laureate, the late Robert Grubbs, PhD, and Julia Kornfield, PhD, from Caltech, revolutionize the post-surgery experience for patients by fine-tuning the visual correction using only ultraviolet light.

The origins of the LAL date back 25 years when Dr. Schwartz first envisioned the concept. As a retinal specialist, he was inspired to create an intraocular lens made of a light-sensitive material that could be adjusted non-invasively using a laser after the eye had healed and the refractive errorwas stable. This idea sparked a fruitful collaboration with Dr. Grubbs, leading to the realization of this groundbreaking technology. The U.S. Food and Drug Administration (FDA) approved the LAL in 2017, offering patients who had undergone cataract surgery the possibility of optimized vision without relying on glasses.

Dr. Schallhorn, who performed the surgery, emphasizes the significant impact the LAL has had on her surgical practice. While existing techniques for selecting intraocular lens power are highly effective, some patients still require glasses. With the light adjustable lens, the risk of such errors is substantially decreased. Patients can now experience clear vision without their cataract and fine-tune their eyesight to their exact preferences, marking a momentous advancement in post-cataract surgical care.

Dr. Schallhorn is enthusiastic about the future of ophthalmology, particularly with the continuous development of new technologies. Reflecting on the field’s progress over the past 50 years, she marvels at how cataract surgery has transformed from a procedure with significant risk of potential vision loss to a routine
outpatient surgery.

Dr. Schallhorn and her colleagues at UCSF, alongside other visionaries in the field, are committed to exploring new ways to treat vision impairment and continue pushing the boundaries
of ophthalmic innovation.
