Crossing the canyon of change: Lessons for leading healthcare innovation.

Healthcare is entering an era of rapid technological advancement, yet history reminds us that technologies rarely transform care through technical excellence alone. Their success depends on leaders who can inspire people to adopt, implement and sustain change. This article uses the evolution of modern cataract surgery as a compelling case study to bring Kotter's eight-step model for leading organisational change to life. Through the metaphor of crossing a canyon, it shows how Sir Harold Ridley and Charles Kelman turned innovation into the global standard of care by creating urgency, building coalitions, communicating a compelling vision, removing barriers and embedding new ways of working. Their story offers timeless lessons for today's leaders implementing new technologies such as artificial intelligence, robotics and precision medicine. Innovation alone does not transform healthcare. People do. The leaders who help others cross the canyon will determine whether today's breakthroughs become tomorrow's standard of care.
