Dr. Srikumaran’s current research interest includes the assessment of corneal transplant outcomes and risk factors for needing corneal transplant through big data sources including Medicare claims data and eyebank data. She recently received the Hoskins Center IRIS Registry Research Fund Award through the American Academy of Ophthalmology to assess disparities in endothelial keratoplasty outcomes the most frequently performed type of corneal transplant surgery in the United States.

Dr. Sulewski’s research focuses on examining outcomes of corneal transplantation using insurance claims data. More specifically, he is studying how indications for full-thickness corneal transplantations (penetrating keratoplasty) have evolved over the past two decades with the advent of endothelial keratoplasty, as well as the long-term outcomes of penetrating keratoplasty in current clinical practice. Currently it is not known whether or not there is a limit to how many penetrating keratoplasty surgeries a patient can receive with reasonable expectation of successful outcome. Dr. Sulewski is also studying repeat corneal transplantation outcomes compared with those of artificial corneal devices (keratoprosthesis) to better define future indications for each procedure.
