Zeiss has introduced the Markerless Cataract Suite, a system the company claims will enable eye surgeons to skip the manual pre-and intra-operative marking steps and manual data transfer involved in cataract surgery. The Suite facilitates markerless toric IOL positioning, allowing surgeons to devote more attention to the procedure, and assisting them to achieve optimal outcomes and greater efficiency.
The Zeiss IOLMaster 500, with its new Option Reference Image (ORI) module captures red-free reference images, replacing the traditional time-consuming steps required to mark the astigmatism axis manually.
A company spokesperson said unlike other systems, the Zeiss IOLMaster 500 does not need an additional stage in the examination to generate a reference image – it is performed directly during the biometric examination.
Once captured, both the reference images and the keratometry data are transferred to the computer-supported Callisto eye OP assistance system, either with the Forum data management system or via USB memory stick. According to Zeiss, this means “all data are available for precise1 and markerless positioning of the toric IOL in colour and with high resolution… in the eyepiece of the Zeiss surgical microscope”.
