Synergies are envisaged between Carl Zeiss Meditec and Carl Zeiss Vision now that the latter is fully owned by the Carl Zeiss group. Carl Zeiss Meditec, which addresses eye doctors and eye clinics with equipment for refractive surgery and other applications, had an exceptionally good quarter in the first three months of its fiscal year through Dec. 31, Zeiss reports. Partly due to positive currency effects, the subsidiary's sales grew by 18.6 percent to €185.2 million and its operating margin (Ebit) rose to 13.0 percent from 12.0 percent n the year-ago period. Ophthalmic systems are the company's largest business unit, representing 47.6 percent of revenues in the quarter.
