After graduating from the University of Alabama School of Medicine in 1991, he began postgraduate studies at Tulane University. Dr. Calonje completed a surgical internship, followed by a research year in the study of the cornea. He started his ophthalmology residency in 1993. After graduating in 1996, Dr. Calonje completed a two-year retina fellowship at the University of Texas.
Dr. Calonje joined Downtown Eye Associates in Houston in 1998. He joined the medical staff at Lyndon B.

Dr. Calonje began his charitable work in 2004 and founded the non-profit Global Vision Foundation in 2008. The goal of the foundation is to diagnose and treat diabetic retinopathy throughout Latin America. The foundation provides equipment and creates self-sustaining ophthalmology clinics. Dr. Calonje has participated in 90 missions to Mexico, examining more than 25,000 patients and performing over 5,000 laser procedures on people who otherwise could not afford them. He hopes the project will one day be global.
