The new IOLMaster 700 is the first device with SWEPT Source Biometry and it has the potential to “significantly improve the refractive results of cataract operations” according to Zeiss, which presented the device at the Summer Congress of the European Society of Cataract and Refractive Surgeons (ESCRS) in London recently.
The device allows irregular geometries of the eye or insufficient fixation to be identified during the diagnosis. Apart from optical biometry, it also offers OCT imaging across the entire length of the eye.
The IOL Master 700 enables cataract surgeons to view the complete longitudinal section of the eye, making irregular eye geometries easier to identify. It is expected that this will facilitate a reduction in refractive surprises. Imaging of the fovea in the macula lutea allows physicians to check for correct fixation.
Zeiss said compared with previous procedures, in which the measurement result was derived from an A scan curve, the image-based measurement with the IOLMaster 700 brings both surgeon and patient added safety, as the expected refractive outcome can be more reliably predicted.
Additionally the device simplifies workflows prior to cataract surgery, eliminating the need for manual pre-operative and intraoperative marking of the astigmatism axis on the patient’s eye before implantation of a toric IOL, as well as manual data transfer.
The IOLMaster 700 is fully compatible with previous versions and provides access to the database of the User Group of Laser Interference Biometry (ULIB).
