Cassini announced key upgrades to the Cassini Corneal Shape Analyzer at the American Academy of Ophthalmology meeting in Chicago. The improvements aim to provide cataract surgeons with ultimate confidence in preoperative diagnostics to help surgeons reduce refractive surprises after cataract surgery, according to a company news release.
Total Corneal Astigmatism (TCA) Algorithm Upgrade: Cassini’s proprietary 2nd Purkinje-based posterior cornea measurements will receive it’s first major algorithm upgrade since the launch of Cassini TCA 2 years ago at the AAO. The new and improved algorithm provides surgeons with customized total cornea information for refractive cataract surgery.
Stability Tracking: Cassini Corneal Shape Analyzer has added software that will provide information on movement of the eye during its acquisition. This will be added to the detailed report that provides confidence factors based on focus, centration, corneal coverage and posterior point detection. When excessive eye movement is detected during an acquisition, a warning signal will be displayed on the Cassini report.
Faster Acquisition Time: The time it takes to acquire a topography examination can have a direct impact on the quality of the ocular surface and the quality of data. New Cassini software provides a better experience for the patient and operator as well as a faster capture to help ensure ocular surface quality during acquisition. Modified workflows will reduce the number of times a patient will need to be re-scanned.
Cassini Insight Diagnostics: Cassini users now have the ability to review important diagnostic and patient flow statistics to measure and further improve user performance.
In a recent retrospective study presented at ASCRS, Cassini TCA achieved 94% accuracy within 0.50 D and 74% accuracy within 0.25 D postoperative manifest refractive cylinder, compared with 84% and 54%, respectively, for the Barrett toric calculator, and 79.4% and 50% for the Baylor nomogram. The research was conducted by Elizabeth Yeu, MD, of Virginia Eye Consultants.
“We are excited to continue to focus on improving the quality of pre-operative data for surgical planning in cataract surgery.” Jeroen Cammeraat, CEO of Cassini, said in the news release. “We have seen many important advances in refractive cataract surgery including femtosecond laser iris registration, arcuate incision guidance and extended-depth of focus toric IOLs. The key to broad adoption of these technologies is the quality of the preoperative data used for surgical planning. We feel we are in the perfect position to help grow this entire segment by providing excellent preoperative corneal information.”
