Cassini allows you to understand
corneal astigmatism,inside and out
Cassini helps eliminate post-op surprises by accurately and reliably measuring Total Corneal Astigmatism (TCA), preoperatively.
Your GPS for Astigmatism Correction
Cassini uses patented multi-colored LED point-to-point ray tracing to provide a GPS-like analysis of the cornea along with high-resolution images utilized for surgical guidance. The unique measuring principle enables highly accurate and repeatable measurements of the TCA.
Total corneal astigmatism (TCA)
Combines the contributions of the anterior and posterior corneal surfaces and accounts for the effect of corneal thickness.
