Manufacturer Reason for Recall | Calibration setting was incorrectly entered during manufacturing causing the optical coherence tomography (OCT) to obtain the incorrect two-dimensional images of ocular structures of the anterior and posterior segments of the eye. |
FDA Determined Cause 2 | Employee error |
Action | On 08/06/2018 the firm sent a Field Safety Corrective Action letter to customers via FedEx Priority Overnight service informing them that based on routine post market surveillance activities, we have information that this specific IOLMaster 700 device is incorrectly calibrated. The calibration value for axial length measurement was not entered correctly in the device settings during
the manufacturing process. The transmission discrepancy leads to an error during the axial length measurement of approx. 0.25mm. A deviation in the axial length of this magnitude results in an error of Single unit. approx. 0.8 Diopter with regard to the intraocular lens. This in turn results in a refractive error of about 0.5 Diopter. The local firm's service organization will remove this device from the field. The device manufacturer will recalibrate the device to ensure it meets specifications.
Hazard involved:
The likelihood of a faulty entered calibration value for axial length measurement in the production process
of IOLMaster 700 is considered rare. The probability of injury, i.e. reduced visual acuity due to the
implantation of a wrong IOL power, is very likely for the affected device, because the axial length of the eye
cannot be measured correctly. The device failure may only be recognized through post-surgical examination.

1 A record in this database is created when a firm initiates a correction or removal action. The record is updated if the FDA identifies a violation and classifies the action as a recall, and it is updated for a final time when the recall is terminated.
