There's something happening in corneal topography

Cassini: a revolution in the making
Meet Cassini, the first corneal topographer to employ breakthrough Color LED Topography (CLT) technology.
The first to deliver submicron accuracy and unprecedented precision (1). The first that is ideal for fitting premium contact lenses, the early diagnosis of corneal diseases including keratoconus, and planning corneal surgery.
Co-developed with Amsterdam VU Medical Center, Cassini uses 672 LEDs in place of the traditional Placido rings (2). The result is a new level of accuracy and precision in corneal height measurement. The benefits for you and your patients:
• CLT measures high and low order aberrations with unmatched detail and precision
• Better prescriptions and better vision correction
• Direct line-of-sight measurement with no need to apply corrective algorithms
• Exceptional ease and precision with dry eyes and post-keratoplasty corneas
• Simple, intuitive design that increases patient throughput
Cassini vs Placido
Cassini’s smart technology can measure high and low order aberrations precisely and in any direction. The rings in Placido topographers, however, limit accurate measurements to the radial direction only. With this fundamental improvement, Cassini sets a new standard.

Easy fitting of premium contact lenses and early detection and progression monitoring with Cassini
Cassini’s CLT technology ensures a better match between cornea and contact lens. It’s simply an easier, faster solution for meeting the growing demand for premium contact lenses such as multifocal, toric, aspheric, and ortho-k lenses. And for standard ones.
