Zhang Dongchang- The -Light Chaser- who breaks through the darkness and bravely climbs the Everest of the disciplines behind his eyes

There’s a saying in the industry that retinal diseases represent the “Mount Everest” of ophthalmology research.

Climbing Everest has always been seen as a symbol of human courage. With extreme weather, a lack of oxygen, a lengthy journey, and ever-changing conditions, each step requires immense effort—only the bravest dare to take on such a challenge.

It’s easy to imagine that scaling the “Everest” of ophthalmology is no small feat. Yet, Professor Dongchang Zhang chose this challenging path right from the start of his career, deliberately focusing on the complex field of vitreoretinal diseases. As a master’s supervisor, committee member of the Ophthalmology Branch of the Chinese Medical Association, and the chief of the Aier Eye Hospital in Shanxi Province, he has dedicated himself to this niche yet crucial area.

**Focusing on the Narrow Path: A Commitment to Retinal Health**

Retinal diseases are known for being some of the most complex and hardest to treat within ophthalmology, often referred to as “vision assassins.” According to the “White Paper on Eye Health in China,” published by the National Health Commission in 2020, over 40 million people in China are affected by retinal diseases, the highest number in the world. The concealed nature of these diseases contributes to the complexity of treatment, creating stringent demands for physicians’ diagnostic skills and hands-on abilities. Data from the 13th Five-Year Plan period show that while the number of ophthalmologists in China has risen to 47,000, there are still fewer than 5,000 specialists focusing on retinal diseases.

Professor Zhang fully understands that the conditions found in the retina are more complex and riskier than those on the surface of the eye. He is aware that becoming an outstanding retinal specialist requires significant time and effort. However, he chose to face the challenges head-on, dedicating himself to this narrow field. In his eyes, preserving the vision of patients is essential to helping them overcome their “darkest moments.”

Reflecting on his career in ophthalmology, Professor Zhang frequently emphasizes the importance of a “comprehensive” approach. He learned fundamental knowledge about ophthalmology in university, and after graduation, he gained practical experience in various specialties including cataracts, strabismus, glaucoma, and retinal diseases. His extensive training has laid a solid foundation for his expertise. Zhang believes that “one who does not plan for the whole is not fit to plan for any part,” a principle that applies equally well in medicine. This wide-ranging perspective has greatly benefited his path in ophthalmic practice.

To this day, Zhang is increasingly confident in his initial choice to pursue the narrow path of retinal disease research rather than entering a more well-trodden field with little chance for breakthrough. For over 40 years, he has embraced the mindset of a lifelong learner, tirelessly advancing in his specialty. He has performed over 20,000 surgeries, serving more than 150,000 patients. In recent years, he has published over 20 papers and has received numerous honors, including the “Shanxi Province May Day Labor Medal” and recognition as an “Outstanding Individual in the Shanxi Healthcare System.”

**Unyielding Commitment: Patient-Centered Care**

When it comes to surgeries, Zhang embodies a spirit of craftsmanship and meticulousness: “I might be more inclined to think deeply, to explore and refine my approach. I love what I do and strive to do it well. Surgery isn’t just a matter of copying and pasting. At a certain stage, I discover new methods—how to best remove lesions and streamline procedures. I aim for perfection.” He believes that precision in retinal surgery is crucial; a slight miscalculation can lead to significant errors, so surgery demands not only skill but also heartfelt attention.

Even now, he maintains this level of dedication in the operating room. For routine retinal detachment procedures, he can complete them in half an hour; for complex vitreous surgeries, what may take others two to three hours, he accomplishes in an hour and a half. His surgical expertise is well-known, earning him the nickname “the scalpel master” within the industry.

Zhang has always adhered to the principle: “Sometimes to heal, often to help, always to comfort.” He believes that a patient’s emotions play a crucial role in treatment; often, a kind word can serve as the most effective medicine. Therefore, he and his retinal team prioritize compassionate care, actively listening to patients’ needs and providing personalized treatment plans.

Take Ms. Shen from Shuozhou, for instance. At over 60 years old and a diabetic for more than twenty years, she began experiencing visual distortions and shadows obstructing her sight. Accompanied by her family, she visited the Shanxi Eye Hospital and met with Professor Zhang, who, upon examination, diagnosed her with retinal branch vein occlusion causing retinal hemorrhage. To control the progression of her condition and protect her existing vision, Zhang performed laser treatment.

“I was extremely impressed by Director Zhang,” recalls Ms. Shen. “He explained everything in detail and even drew diagrams for clarity; he was exceptionally patient.” After her first laser treatment, her vision improved significantly, leaving her with such a positive impression that she eagerly recommends him to family and friends facing eye issues, saying, “Go to Taiyuan, find Professor Zhang! He’s an exceptional doctor!”

Years later, Ms. Shen experienced another decline in vision but delayed seeking treatment for various reasons. One day, her right eye suddenly lost all vision, leaving her in panic. With her family’s support, she returned to the Shanxi Eye Hospital, only to find that Professor Zhang had moved on.

“Not being tech-savvy, I asked around until my son helped me check online, and I was amazed by how accessible everything is now, including booking appointments,” she said, noting the advancements in eye care technology over the past decade. After comprehensive tests, including a wide-angle retinal scan and OCT, she was diagnosed with diabetic retinopathy in both eyes (right eye stage VI, left eye stage IV). To minimize surgical trauma while effectively managing her condition, Zhang performed an advanced 27G vitreous surgery.

During a follow-up the day after surgery, the retinal hemorrhage had been completely cleared, and due to the small incision, the recovery was swift with no complications. By the time she was discharged, her vision had significantly improved. Reflecting on her experience, Ms. Shen expressed, “I couldn’t believe that even after all these years, Director Zhang still remembers me. His familiarity with my history eased my anxiety about the surgery, and his professionalism and patience made me feel secure.”

Upon becoming the director of Aier Eye Hospital in Shanxi Province, Professor Zhang’s schedule became extremely demanding, juggling clinical duties, research, administration, and teaching, often moving between consultation rooms, operating theaters, hospital wards, and various academic conferences. Despite the intensity of his work, he always prioritizes his patients, saying, “Before every surgery, I consider all the details and potential emergencies, as well as individual patient differences. Afterward, I must focus on all reactions and symptoms. If I have any spare time, I’m reading or studying; I can’t afford to fall behind.”

After four decades in medicine, Professor Zhang’s passion for ophthalmology remains strong. “When a patient’s vision improves by 0.1 or even 0.01, I feel like I’ve helped bring someone back from ‘blindness.’ That sense of accomplishment drives me. Every individual’s journey of self-improvement has a pivotal point, and for me, making sure every patient can regain their sight and lessen their suffering is my greatest wish.”
