The CIRRUS™ family of OCT instruments offers a choice of high-quality OCT clinical solutions to assist you in the diagnosis and management of glaucoma and retina disease across all levels of care.
Keeping both your patients and your practice in mind, Carl Zeiss Meditec, the global leader in OCT, developed Cirrus HD-OCT. not only does it supply you with bar setting imagery, it delivers detailed diagnostic and change analysis you can rely on time and again. Along with its small footprint and fast capture speeds, Cirrus is designed to improve workflow efficiency while helping you deliver better care to your patients.
The FastTrac™ retinal tracking system is one of the most significant enhancements ever developed for the Cirrus OCT product line in that it reduces eye motion artifacts without sacrificing patient throughput and well known Cirrus ease-of-use. It does this by utilizing a proprietary scan acquisition strategy, high speed 20 Hz LSO camera, and single-pass alignment scanning. FastTrac also allows the operator to scan at highest resolution at the same location at each visit. In addition, the new Macular Thickness OU Analysis gives you a compilation of macular thickness for both eyes on the same page.
Cirrus gives you the ability to view pathologies from multiple vantage points-and with a range of at-a-glance visualization formats, you’ll be better able to assess your patient’s condition and determine the appropriate course of action.
