🎙️ The Story Behind Dua's Layer, Research & Scientific Curiosity | Prof Harminder Dua

What does it take to make a discovery that changes an entire specialty? Every ophthalmologist has heard of Dua's Layer. It is taught in textbooks, discussed in conferences, and has influenced the way we understand corneal anatomy and surgery. But behind every landmark discovery lies a story that is rarely told—a story of curiosity, observation, persistence, and the willingness to question what everyone else accepts as fact. In this episode of Eye On It – Ophthalmology Unfiltered, I sit down with Professor Harminder Dua, one of the world's most respected corneal surgeons, clinician-scientists, and educators, for a fascinating conversation that goes far beyond the discovery that bears his name. Professor Dua takes us back to the journey that led to the identification of Dua's Layer—what sparked the idea, the evidence that supported it, the scientific debate that followed, and how our understanding of this anatomical plane continues to evolve today. Rather than viewing scientific discovery as a single defining moment, he explains why it is often the result of years of careful observation, collaboration, and asking better questions. We also discuss the latest developments surrounding Dua's Layer and how ongoing research continues to refine our understanding of corneal anatomy. Science is never static, and Professor Dua shares why every discovery should remain open to further investigation as new evidence emerges. For young ophthalmologists, researchers, fellows, and residents, this episode offers invaluable lessons on building a meaningful academic career. Instead of chasing publications for the sake of numbers, Professor Dua explains why the most impactful research begins with genuine clinical curiosity. He discusses how young clinicians can identify worthwhile research questions, why some projects create lasting change while others are quickly forgotten, and how persistence often matters more than immediate success. One of the most practical parts of our discussion focuses on research funding and choosing research topics. Professor Dua shares his perspective on research grants, how investigators should approach funding opportunities, and why financial support plays such an important role in advancing innovation and improving patient care. For anyone hoping to build a career in clinician-scientist research, his advice is both practical and inspiring. Throughout the conversation, Professor Dua reminds us that research is not reserved for a select few working in large academic institutions. Every clinician who pays close attention, asks thoughtful questions, and challenges existing assumptions has the potential to contribute to the advancement of medicine. This conversation isn't simply about one anatomical discovery. It's about developing the mindset that allows discoveries to happen. Whether you're a medical student beginning your journey, a resident learning the fundamentals, a fellow developing your subspecialty expertise, or an experienced consultant interested in research and innovation, Professor Dua's insights offer timeless lessons that extend well beyond ophthalmology. In this episode, we discuss: • The story behind the discovery of Dua's Layer • The scientific journey from observation to publication • How the understanding of Dua's Layer has evolved over time • The latest developments and ongoing research surrounding the layer • Why scientific discoveries continue to evolve • How young ophthalmologists should approach research • Identifying meaningful clinical questions worth investigating • The importance of curiosity in scientific progress • Research grants and funding opportunities • Building a career as a clinician-scientist • Mentorship, collaboration, and lifelong learning • Advice for the next generation of ophthalmologists Professor Dua's career demonstrates that the greatest advances in medicine often begin with a simple question: What if what we currently believe isn't the complete picture? That willingness to question established knowledge has shaped not only his own career but also the way countless ophthalmologists think about the cornea today. 🎧 Listen wherever you are: YouTube Spotify Apple Podcasts Eye On It – Ophthalmology Unfiltered by Dr Harika Reddy brings you long-form conversations with the people shaping the future of eye care.
