AstraMax
AstraMax: is a new generation 3-D corneal topography with enhanced resolution ideally suited for custom cornea-based treatment. AstraMax is a unique, patented three-camera imaging system that uses stereo ray tracing for high-precision, patient-specific corneal measurements. Patented polar grid yields critical measurements to measure complex corneal shapes. High-definition graphics provide eye simulations and 3-D surface modeling.
The AstraMax is the only topographer capable of measuring, recording and photographing scotopic pupil size and it’s location relative to visual axis. The system has an integrated infrared light that captures the pupil’s properties with three cameras in dark room or selected illumination. AstraMax provides excellent posterior corneal data and topography. This is important information in the analysis of the quality of vision
The built in pachymeter measures the thickness of the cornea, eliminating patient eye movement - a significant variable of inaccuracy. AstraMax’s three cameras triangulate views of several narrow projected slit beams of light as they pass over the cornea. The stereo cameras see these slit beams as they pass through various cross-sections of the cornea, very much like a multi-angled parrallele- piped on a slit lamp - this enables a precise measurement of thickness every points the beam passes through. The value and precision of the diagnostic information acquired, processed and registered with the AstraMax is indispensable for any corneal specialist and refractive surgeon.
AstraMax introduces stereopsis to topographic measurements, simultaneous multidirectional cameras polar grid technology and scotopic pupil size determination. Acquisition and processing of anterior and posterior precise data and understanding its effect on corneal biomechanics will significantly enhance the corneal surgeons’ capabilities to improve the outcome of refractive surgery. With these features and benefits it would be difficult to justify not incorporating the AstraMax Stereotopographer into your practice. Expanded diagnosis provides greater anterior coverage and includes key areas that may be missed by traditional placido systems. Six complex operations are performed in one exam, including posterior and anterior corneal topography, limbus-to-limbus topography, corneal wavefront error and scotopic and photopic pupillometry.
AstraMax has an extremely rapid acquisition time. More than 35,000 measuring points are captured in less than 0.2 seconds, which significantly increases spatial resolution and coverage. Rapid acquisition time increases accuracy and eliminates the need for head strapping during the exam.
