Specular miscroscope

■ The EM-3000 specular microscope, from Tomey, which employs an LED light source instead of a conventional xenon lamp, features an auto-alignment and auto-shot function (manual photography is possible) and captures a sequence of 15 images. It offers seven fixation points for a wide area of image acquisition — even on an irregular corneal surface — while simultaneously measuring corneal thickness, the company says. The device's color touch screen displays the most accurate photo.

Lab software

■ The Digiform Plus software, from Briot, enables the company's Accura edgers (Silver, Silver Plus and CX) to perform shape modification (proportional, vertical and horizontal) for customized jobs.
