Founded in 1975, Katena Premium Reusable Instruments is the brainchild of Kate Tiedemann. Kate left post-World War II Germany in 1955 speaking very little English. Over the course of the next two decades, Kate worked incredibly hard and eventually progressed into the medical device industry, working for three different micro-surgical instrument companies before founding Katena (short for Kate North America). While many aspects of the Katena brand have changed over the last 5 decades, the Katena brand still represents a commitment to excellence, exceptional quality, and valued surgeon partnerships. We continue to collaborate with surgeons and instrument makers to deliver high-precision reusable instruments that advanced ophthalmic surgery.
