Cassini is a first-of-its-kind Corneal Shape Analyzer based on Color LED Technology. Cassini measures the axis and magnitude of corneal astigmatism and is important for premium IOL planning. Cassini complements the premium refractive-refractive platform. Cassini was listed in “Best Technology of 2014” and the “Innovation Awards of 2014”. The biggest impact from the unique color-LED based ray-tracing technology will come from providing key information for improving patient outcomes based on Cassini’s Total Corneal Astigmatism (TCA) capabilities. Cassini’s Total Corneal Astigmatism gives refractive-cataract surgeons important information for both anterior and posterior corneal astigmatism, yielding highly accurate correction of Total Corneal Astigmatism. Current cataract surgery protocols mostly take into account anterior astigmatism. Correcting astigmatism is important for achieving superior outcomes. i-Optics International Mauritskade 35 2514 HD The Hague The Netherlands Phone: +31 70 3993112 Fax: +31 70 4155215 info@i-optics.com i-Optics USA 1 Wall Street, 6th Floor Burlington, MA 01803 USA Phone: 888-660-6965 info@i-optics.com

REFRACTIVE OUTCOMES
When it comes to managing astigmatism,
posterior curvature matters
• In Koch et al., anterior corneal measurements
underestimated Total Corneal Astigmatism
(TCA) by 0.22 D @ 180° and exceeded 0.50 D
in 5% of eyes1
• Selecting toric IOLs based on anterior corneal
measurements alone could lead to overcorrection in
eyes that have WTR astigmatism and undercorrection
in eyes that have ATR astigmatism1
