High-Intensity, Medical Fiber Optics, and Nanobiophotonics. The FDA is developing innovative methods for evaluating the safety and effectiveness of new optical therapeutic technologies and devices including medical therapeutic lasers, fiber-optics, and new therapeutic monitoring and bio-sensing systems. The United States is the global leader in medical device innovation and the Food and Drug Administration's (FDA) Center for Devices and Radiological Health (CDRH) is committed to assuring that American patients have timely access to important new technologies and next-generation products without compromising their safety. Each year, millions of American patients benefit from innovative medical devices that reduce suffering, treat previously untreatable conditions, extend lives, and improve public health. CDRH is responsible for advancing public health and facilitating innovation to help bring novel technologies to market and make the medical devices that are already on the market safer and more effective.
