“Vision is a crucial sense for everyone, and it is both a privilege and an honor to play a role in preserving and restoring something so essential to daily life. Although I find joy in performing microsurgery and working with ever-advancing technologies in ophthalmology, my most cherished responsibility as a retinal physician is enhancing the quality of life of my patients.”
