Brandon D. Ayres, MD, continues this series exploring the best practices in keratoconus management by inviting John Berdahl, MD, to share his experience with crosslinking. The two discuss the bilateral nature of keratoconus and share their thought processes and approaches for managing the disease in both eyes. They also review the role of the referring optometrist and how to become a keratoconus detective to find proof of disease progression before treatment.
