Ziemer USA, Inc. is partnering with ConeaGen to launch a new module for its GALILEI diagnostic platform: GALILEI corneal tissue addition keratoplasty (CTAK).
Start with a rundown on these players.
What to know about CorneaGen: The Seattle, Washington-headquartered eye bank is the largest global provider of corneal transplant tissue, with laboratories located across the United States and advanced tissue processing methods available seven days a week.
As for Ziemer USA: This is a privately-held medical device subsidiary of the Swiss-based Ziemer Group specializing in developing and manufacturing ophthalmic equipment and surgical technologies.
- Among these products: laser systems and diagnostic devices.
Next: Talk about the GALILEI diagnostic platform.
The FDA-cleared GALILEI platform is an all-in-one, comprehensive diagnostic device available in two new next-gen variations:
- GALILEI G4 ColorZ
- Combines Dual Scheimpflug tomography and placido topography
- GALILEI G6 ColorZ
- Integrates optical biometry with Dual Scheimpflug tomography and placido topography
Among their clinical applications: refractive screening, corneal asymmetry analysis, and keratoplasty planning and follow-up (see here for others).
And what does the GALILEI G4 offer?
The GALILEI G4 is designed with a state-of-the-art camera and high-definition (HD) monitor that provides multi-layer TopView imaging in “vibrant colors and with a higher contrast.”
A few key components and offerings of this platform:
- Placido topography: Provides data on the anterior curvature of the cornea—and precisely detects anterior surface irregularities as well as tear film quality.
- Dual-Scheimpflug tomography: Accessible via Ziemer’s FEMTO Z8 NEO, a portable (with wheels) femtosecond laser platform, and includes a 3D anterior chamber analysis
- 1st Purkinje reflex: To which all maps and data are aligned, this reflex is the closest to the visual axis; generates surface data and consistent alignment when comparing a consecutive measurement series over time
- Color TopView images: Communicates with Ziemer’s FEMTO Z8 platforms
And how does this differ from the GALILEI G6?
The G6 version of the platform is equipped with all of the capabilities of the G4—plus the inclusion of an optical biometer to measure lens thickness and axial length for the IOL power calculator.
More specifics on this additional component: The platform’s optical coherence tomography (OCT)-based optical A scan measures the following parameters within the same exam:
- Central corneal thickness
- Anterior chamber depth
- Lens thickness
- AL
An added bonus: LT and AL can be measured together using “precise anterior and posterior corneal power maps and corneal wavefront analysis.”
Duly noted. Now what do we know about this CTAK module?
First: It’s being offered in combination with Ziemer’s FEMTO LDV Z8 femtosecond laser platform.
The details: The new module combines high-resolution corneal tomography with laser-guided stromal inlay preparation to “deliver an anatomically optimized and patient-specific approach to corneal reshaping,” according to Peter S. Hersh, MD, FACS, director of Cornea and the research division at the Cornea & Laser Eye Institute (CLEI).
- The intent: To further advance, provide, and enable visual function in keratoconus patients.
Nice! So how many modules are available with the GALILEI platforms now?
From refractive to cataract displays, quite a few.
See here for the complete rundown on each platform.
And if I already own a GALILEI platform, how do I access this new module?
As the module is now available within the U.S., clinicians simply need to update the software on their GALILEI platform.
