    Narratives

    Additional Manufacturer Narrative · 1

    THE NAVILAS LASER SYSTEM WAS RETURNED TO OD-OS GMBH, CLEANED, DECONTAMINATED, AND EVALUATED. THE FINAL INVESTIGATION CORROBORATED THE RESULTS FROM THE INITIAL INVESTIGATION WHERE THE INVALID CALIBRATION WAS REPRODUCED, MEASURED, AND CONFIRMED. THE ACTUAL LASER MISPLACEMENT WAS EQUIVALENT TO THE THEORETICAL CALCULATION. IN ADDITION, THE OPTICAL HEAD WAS SUBJECTED TO COMPREHENSIVE TESTING AND NO MECHANICAL FAULTS WERE IDENTIFIED. THE SYSTEM WAS REPAIRED AND RECALIBRATED AND PASSED FINAL INSPECTION TESTING. IN CONCLUSION, THE DEVICE MALFUNCTION WAS CONFIRMED TO BE SOLELY ATTRIBUTED TO INVALID CALIBRATION PERFORMED BY FOREIGN SERVICE PERSONNEL. MANUFACTURER'S COMPLAINT #: (B)(4).

    Description of Event or Problem · 1

    ON (B)(6) 2017 A PATIENT WITH PREEXISTING PERIPHERAL RETINAL TEARS UNDERWENT ATTEMPTED LASER PHOTOCOAGULATION IN THE RIGHT EYE. THE TREATMENT WAS BEING PERFORMED IN ORDER TO PREVENT RETINAL DETACHMENT. DURING THE PROCEDURE, THE SURGEON REPORTS THAT THE TREATMENT WAS NOT DELIVERED TO THE TARGET AREA, SO HE INCREASED THE LASER ENERGY AND TREATED THE PATIENT A SECOND TIME. AFTERWARDS THE SURGEON REPORTS THAT THE LASER TREATMENT WAS DELIVERED POSTERIOR TO THE TARGET AREA, THEREFORE LEADING TO PHOTOCOAGULATION OF TISSUE NOT INTENDED TO BE TREATED IN THE PERIPHERAL RETINA. THE RETINAL IMAGE WAS REVIEWED BY THE OD-OS MEDICAL MONITOR (RETINA SPECIALIST) WHO CONFIRMED THE TREATMENT AREA REMAINED WITHIN THE PERIPHERAL RETINA AND THERE WAS NO EVIDENCE OF DAMAGE TO THE MACULA OR FOVEA AND NO EVIDENCE OF A VITREOUS HEMORRHAGE. ADDITIONAL INFORMATION HAS BEEN REQUESTED FROM THE SURGEON. AT THIS TIME, THERE IS NO REPORT OF INTERVENTION OR ADVERSE IMPACT ON VISION.
