VX130“THE VX130 COMBINES STATE-OF-THE-ART TECHNOLOGIES (SCHEIMPFLUG SCAN CAMERA, NON-CONTACT TONOMETRY, ABERROMETRY, CORNEAL TOPOGRAPHY) AND PROVIDES ESSENTIAL DATA FOR AN IMPROVED TREATMENT OF PATIENTS, REGARDLESS OF THEIR CONDITION AND OCULAR HISTORY. WITH FULLY AUTOMATED MEASUREMENTS, THE VX130 ISTHE IDEAL PATIENT MONITORING SYSTEM.”
REFRACTIVE SURGERY Pre- and Post-Op
Complete analysis of the cornea
Combination of data obtained by the Scheimpflug cameraand corneal topography data, thickness maps and elevationmaps can be obtained on a broad corneal surface.
