Descemet Stripping Only (DSO)

Kathryn Colby, MD, PhD, is the Director of NYU Langone’s Eye Center and the Elisabeth J. Cohen, M.D. Professor of Ophthalmology and Chair of the Department of Ophthalmology at the NYU Grossman School of Medicine. Dr. Colby pioneered the Descemet stripping only (DSO) procedure for Fuchs dystrophy, which is the most common reason for a corneal transplant in the United States. DSO allows a patient’s own cells to rejuvenate their cornea, rather than relying on a donor cornea. In addition to her clinical work, Dr. Colby has authored more than 100 scientific studies and 7 books, and contributed chapters to 24 books. She lectures around the world on a variety of corneal topics. Dr. Colby has held leadership positions in several national and international societies and is currently serving as Vice Chair of the EBAA Research Committee. Dr. Colby is devoted to enhancing the status of women in ophthalmology.

Anjali Ferris, MD, is a research fellow at NYU Langone Health. Dr. Ferris completed her medical degree at Loyola University Chicago Stritch School of Medicine. She will begin her ophthalmology residency with NYU Langone Health in July 2025.
