Nina Ni

Nina Ni, MD

Dr. Ni attended Harvard College and Yale School of Medicine. She completed her ophthalmology residency at the world-renowned Wills Eye Hospital in Philadelphia, followed by a fellowship in Cornea, External Disease and Uveitis at the Proctor Foundation/UCSF, where she was awarded the Claes Dohlman Fellowship Award (given to one outstanding cornea fellow in the nation annually).

Her special interests will be medical and surgical management of diseases of the cornea and external eye, cataract surgery, and complex cases involving the front part of the eye. This includes procedures such as corneal transplants, complex and premium cataract surgery using femtosecond laser technology, and reconstruction after trauma or previous surgeries. During her training, she was privileged to run an eye emergency room, provide refractive surgery for our armed forces in Texas, and contribute to ophthalmic care for the local population in Tenwek, Kenya. Here at ECI, she has the opportunity to continue the tradition of providing eye care to those most in need. She also serves as adjunct faculty at our local Touro University, where she treasures the chance to help educate the next generation of young physicians.
