FRANKFURT (dpa-AFX Broker) - Papers of Carl Zeiss Meditec have been under pressure on Tuesday morning in quite high trading volume. The shares of the medical technology company fell by up to 5 percent towards their simple 200-day line. One stockbroker spoke of fears that intraocular lenses, a very profitable product for Zeiss, could be placed on China's VBP list. With Volume-Based Procurement (VBP), China aims to purchase higher volumes at lower prices in the area of high-value medical products. In this system, pharmaceutical companies have to repeatedly grant high price discounts for older drugs if they want to get anywhere at all./ag/mis
