Description
Ziemer GALILEI G4
“All-In-One Solution, From Refractive to Cataract Surgery”
The Galilei G4 is an all-in-one solution, from refractive to cataract surgery along with a modular system that can be upgraded according to your needs – anytime. With 3 new high-definition cameras – 2 Scheimpflug and 1 top view – NEW automatic surface alignment and reduced light intensity for the patient’s comfort, it really is the only true solution. The Galilei G4 combines state of the art technology like Optical Biometry and Placido Topography, ideal for a variety of applications including Refractive & Cataract evaluation, which allows practitioners to carry out effective and precise refractive and cataract surgery planning. It makes it possible for examiners to obtain all the necessary measurements all on one convenient system.
Features:
- Combined Imaging Technologies: The G4 integrates Placido disc topography for anterior surface data with Dual Scheimpflug tomography to capture the posterior corneal surface.
- Total Corneal Wavefront: It provides ray-traced total corneal wavefront measurements, offering precise data on high-order aberrations for predictable surgical outcomes.
- Keratoconus Screening: The device offers a complete dataset, including precise posterior corneal curvature and elevation data, to help detect early signs of keratoconus.
- IOL Calculation: The G4 is used for comprehensive IOL planning, with a licensable module that includes the Shammas no-history formula for reliable IOL prediction in post-refractive patients. **
- Corneal Surgery Planning: It provides data for planning and follow-up of corneal implants and keratoplasty (corneal transplants), allowing for close control of anterior and posterior corneal astigmatism.
- Eye Motion Compensation: The patented iris-based system compensates for eye movements, ensuring accurate measurements even in challenging patients like children or the elderly.
- Modular System: The G4 is a modular device that can be upgraded with different software modules to expand its capabilities.
Applications in Eye Care
- Refractive Surgery: Planning and evaluating LASIK, PRK, and other refractive procedures by analyzing total corneal power and aberrations.
- Cataract Surgery: Providing comprehensive data for planning, especially for selecting premium IOLs, including in post-refractive cases.
- Therapeutic Procedures: Assisting with the planning and evaluation of corneal procedures like corneal inlays and keratoplasty.
Unique Technology
Reliable Surface Data For Refractive And Corneal Surgery – The GALILEI G4 integrates Placido disc topography and Dual-Scheimpflug tomography in one device. This combination of technologies allows for a complete analysis of both the anterior and the posterior corneal surface. The simultaneously recorded Dual-Scheimpflug images produce reliable pachymetry and posterior curvature data, whereas the Placido ring images provide highly accurate and central anterior corneal curvature data fitted to the anterior corneal surface.
Patented iris-based eye motion compensation – Small to moderate eye motions which can lead to clinically relevant surface curvatures cannot be prevented especially in elderly patients or children. The GALILEI G4 comes with a patented iris tracker which compensates for eye motion. Different than other topography and tomography devices that align data to the pupil or the apex of the cornea, the GALILEI G4 aligns all data to the visual axis using the 1st Purkinje image. This ensures consistent alignment when comparing a series of consecutive measurements over time.
Ray-traced Total Corneal Wavefront solution – With its powerful ray-traced Total Corneal Wavefront solution, the GALILEI G4 precisely measures high order aberrations for highly predictable outcomes in cataract surgery. The high order aberration display helps identifying the most suitable IOL for every patient.
