“As a dedicated refractive cataract surgeon, the integration of Cassini diagnostics with CATALYS™ therapeutics has been an extraordinary advance in my management of astigmatism at the time of cataract surgery. The Cassini Ambient seamlessly provides the preoperative anterior and posterior astigmatism and uses iris registration to compensate for cyclorotation during the femtosecond laser procedure – increasing the accuracy of cylinder management for astigmatic keratotomies and toric IOLs. I can finally stop using the archaic method of marking corneas with a gentian violet pen.”

Eric Donnenfeld, MD
OCLI Vision, USA

“The accuracy and precision of the Cassini Ambient is truly impressive. The seamless connectivity and registration with my CATALYS™ instills great confidence.”

Trey Bishop, MD
Bishop Eye Center, SC, USA

“The direct entry of preoperative data, onboard nomogram and import of iris registration makes the Cassini and CATALYS™ combination historical in increasing operational efficiency.”

Professor Burkhard Dick
University Eye Hospital, Bochum, Germany

“I no longer spend any time on manually marking nor having to rely on guesswork around accurate incision placement and toric axis alignment. Cassini saves me so much time!”

Carl J. May, MD
The May Eye Center, PA, USA

“Astigmatism management was previously an unmet need, due to the cataract surgeons’ discomfort with the tools and techniques available to us to deliver what we’ve promised to our patients. The Cassini Ambient integration with the CATALYS™ cOS 6.0 gives us the ability to confidently recommend astigmatism management as part of the cataract procedure, powered by this new technology that helps reduce transcription errors and increase accuracy and precision.”

Wendell J. Scott, MD
Mercy Clinic Eye Specialists, MO, USA

The Cassini’s precise LED-reflection based anterior and posterior k’s, seamless pre-op data and patient information integration with my CATALYS™ and accurate iris registration all lead to superior outcomes.”

Tal Raviv, MD, FACS
Eye Center of New York, NY, USA

“The Cassini Ambient has taken astigmatism management to a new level in my refractive cataract surgery practice; measuring total corneal astigmatism and having iris registration connectivity with my CATALYS™ boosts precision and efficiency.”

Jared Younger, MD
Orange Coast Eye Center, CA, USA

“Cassini is at the forefront of modern eye care. It’s a first-of-its-kind device designed to measure Total Corneal Astigmatism (TCA) – I find this to be critical information for me to confidently plan and perform my procedures.”

Omar F. Almallah, MD, FACS, FABES
Susskind & Almallah Eye Associates, NJ, USA

Driven by insatiable curiosity, the love of science and passion for vision, Cassini has been dedicated to pushing the boundaries on personalized, thorough and accurate corneal diagnostic solutions for well over a decade.

Independently, and in collaboration with our vision-care partners, we strive to make the gift of lifelong sight accessible and possible the world over.

As innovative and progressive thought-leaders, we empower surgeons with the efficient, user-friendly tools, collaboration and support they need to make confident decisions for optimal outcomes. We care, and we love those who care as much as we do. Our partners in vision-care share our beliefs and together we are a formidable connection.

What top surgeons
say about Cassini

“Cassini is a better alternative for toric IOL planning and, as such, stands to pave the way for surgeons who have been hesitant to implant these premium lenses.”

Douglas Koch, MD
Baylor College of Medicine, Houston, TX, USA

“Superior in central corneal measurement to Placido and Scheimpflug in case of high irregularity.“

A. John Kanellopoulos, MD
Laservision Eye Institute, Athens, Greece
New York University Medical School, New York, USA

“Cassini is a game-changer, it’s a reliable and great brand that has done amazing things for my practice.”
