In this high-tech, digital age, over 75% of patients are now searching for health information online. The internet has become the modern exam room. As a practicing eye surgeon who is also active on social media, I am passionate about eye health education and sharing medical information in a way that is easy to understand, sometimes fun, and always backed by science and evidence-based medicine. I am honored to be a member of the Medical Review Board for Verywell and fully support its mission to bring trustworthy, practical, and up-to-date health information to millions of people worldwide.
