Biography
Carlos Quezada-Ruiz, M.D. is a vitreoretinal surgeon, researcher, and Assistant Professor of Ophthalmology at the Instituto de Oftalmología Fundación Conde de Valenciana in Mexico City. An active clinician for more than 15 years, he cares for patients and their families while teaching and mentoring retina fellows and residents. Guided by a strong purpose to help people live better lives through better vision, he is passionate about advancing diversity in ophthalmology, improving health equity and access for people with retinal diseases, mentorship, and building highly effective, purpose-driven teams.
For over a decade, Dr. Quezada-Ruiz has also been a leader in drug development, holding senior roles at 4D Molecular Therapeutics, most recently as Ophthalmology Therapeutic Area Head, and at Genentech/Roche, where he led global clinical development of Vabysmo and Susvimo through their initial regulatory submissions, approvals, and commercial launch. At 4DMT, he leveraged his regulatory expertise and strategic leadership to prioritize the ophthalmology pipeline and secure FDA and EMA alignment on global Phase 3 programs, advancing 4D-150 in nAMD and DME.
Committed to scientific progress and education, Dr. Quezada-Ruiz has served on scientific committees and lectured across the United States, Latin America, and Europe. He is board-certified by the Mexican Council of Ophthalmology, the International Council of Ophthalmology, and the Educational Commission for Foreign Medical Graduates. He has authored more than 40 peer-reviewed publications, serves as an editorial board member and peer reviewer, and is an active member of SMO, AMR, ACOREV, AAO, ARVO, PAAO, and ASRS.
His contributions have been recognized with honors including the ASRS Senior Honor Award (2019), ASRS Honor Award (2016), the Gillingham Pan-American Fellowship (2013), the Leonard Ellen Ocular Pathology Award (2013), the Roche Award of Excellence (2023), Genentech’s Medical Excellence Award (2023) and ACOREV Honorary Member Award (2025).

Outside of medicine, Carlos enjoys reading, practicing martial arts, playing the guitar, helping others, and enjoying life with his wife and three children.
