The University of North Carolina Department of Ophthalmology staffs two American Board of Ophthalmology board-certified, fellowship-trained ophthalmologists who specialize in medical and surgical management of injuries, allergies, inflammation, dry eye disease (DED), dystrophies and other conditions that harm the clear outer layer at the front of the eye — the cornea.

Our faculty corneal disease experts Assistant Professor Hussam E. Banna, MD, and Assistant Professor Sinthu Ranjan, MD, offer consultative and diagnostic services and see patients for corneal disease at UNC Kittner Eye Center in Chapel Hill. The Department’s two corneal disease specialists additionally practice at other UNC Health locations across the Triangle where UNC Ophthalmology offers medical and surgical clinical services: 1) UNC Eye Holly Springs (Banna); 2) UNC Park Ophthalmology in North Raleigh (Ranjan); and 3) UNC Hospitals Hillsborough (Banna, Ranjan). Dr. Banna’s scope of corneal disease practice includes cornea cross-linking and keratoconus management.  Dr. Ranjan’s procedural scope of practice includes corneal transplantation.
