Bradley Powers Barnett, MD, PhD

Assistant Professor of Ophthalmology

Dr. Barnett is a cornea surgeon who treats patients with cataracts, corneal diseases and ocular surface diseases such as dry eye disease. He views himself first and foremost as a partner in meeting the visual goals of each of his patients. He was attracted to ophthalmology, specifically cornea and external disease, as people recognize their own symptoms prior to coming to visit him. This creates a unique relationship in which patient and clinician are mutual partners in achieving health goals.

He prides himself on providing transformative, up-to-date, safe and effective treatments in various forms of ocular surface disease. In the same way, he is wholly committed to achieving the visual goals of his patients using the latest cataract surgery techniques including laser assisted cataract surgery, premium intraocular lenses to treat presbyopia and astigmatism as well as intraoperative aberrometry. He is well versed in the most advanced vision correction surgery techniques for LASIK and PRK, as well as INTACS and corneal cross-linking. He enjoys challenging cataract, and anterior segment cases including traumatic cataracts, subluxed lenses, dislocated intraocular lenses, and iris reconstruction cases. In addition, he is well versed in a breadth of corneal transplantation techniques including DSAEK, DMEK, PKP and limbal stem cell transplantation. He is proud to be part of the culture of innovation and standard of excellence that is characteristic of Duke Eye Center.

As a physician-scientist, Dr. Barnett focusses on developing novel therapeutics and drug-delivery strategies to treat ocular surface disease, as well as novel devices and surgical procedures to advance the effectiveness and safety of keratoplasty and cataract extraction and intraocular lens implantation. He is an inventor on numerous awarded patents and numerous pending patents. He has extensively published in the fields of nanotechnology, biomaterials and pharmacology including manuscripts in Science and Nature Medicine. For his commitment to physician- scientist pursuits he was awarded a Howard Hughes Medical Fellowship, a Pfeiffer Foundation Fellowship and the Claes Dohlman Fellowship.

Dr. Barnett’s dedication to research and clinical care also inspires his teaching. For his commitment to teaching and training, he has received the Wilmer Eye Institute Richard Green Teaching Award. He has also authored numerous book chapters on surgical technique and clinical imaging. In addition to clinical, research and teaching pursuits, Dr. Barnett enjoys mountain biking and hiking the Carolina wilderness with his wife and Yorkie, Chester. He is also a lover of music and film, and plays guitar, bass and drums.
