Overview
I am dedicated to helping people of all ages preserve, restore, and maximize their vision. I perform all types of refractive surgery (LASIK, PRK, ICL, and refractive lens exchange) so that I can offer my patients a treatment customized to their needs. I also specialize in cataract surgery, including premium lenses, corneal transplants, and other procedures of the eye surface. In addition to my work at Duke Health, I am heavily involved in humanitarian eye care in Africa and around the world. I am the founder of HelpMercy International, a founder of the Moran CORE education website, and was one of the surgeons featured in the award-winning movie Duk County. I live in Chapel Hill with my wife and three children who helped me write and produce a full-length musical called “RISE.” We also enjoy cycling, rock climbing, and building and playing guitars, basses, and drums.

Duke Ambulatory Surgery Center Arringdon
I am a native North Carolinian, having grown up in Raleigh, NC. I went to UNC-Chapel Hill for my undergraduate degree in Biology and attended Medical School there as well. I remained at UNC to complete my residency in Ophthalmology. I then came to the school with a deeper shade of blue to complete my fellowship year in Glaucoma and joined the faculty at the Duke Eye Center in July of 1996. I knew I wanted to be an eye doctor in 9th grade when I received my first pair of glasses. I could see clearly now, and I decided to dedicate my life to helping others improve and/or maintain their vision. My approach with patients is to put them at ease, as often they are concerned about going blind. I give them an opportunity to share with me their concerns, then I make recommendations based on the best available literature and my personal experience.
