During processing of this complaint, attempts were made to obtain complete event, patient and device information.The lens was discarded by the clinic; thus, a proper device analysis could not be completed.It was reported that our recommended z28 cartridge and r28 injector system was used to deliver the lens.We know that there was no damage noted to the lens during the inspection prior to use or during preparation for use, which indicates that a product deficiency did not contribute to the reported issues.Additionally, lenses are 100% inspected before they leave our manufacturing site.Therefore, we are confident that the lens was processed per standard operation procedures and inspections, and met all of the criteria for release.Markings from the folder or injector are known to be caused by numerous factors including, but not limited to: loading strategy, lens placement technique, accessory device support, poor handling during folding and inserting.The device history records were reviewed and there were no non-conformities or deviations noted during the manufacturing of the lens that would have contributed to the nature of this complaint.The dfu provides precautions for the lens handling and injection process by stating that: "improper handling of this lens may cause damage to the haptics and the optics." we have reviewed the information provided and at this time there is no indication of a product quality issue with the respect to the manufacturing, design, or labeling of the lens.No malfunction of the lens can be confirmed to have caused or contributed to the reported issue.The reported issue appears to be related to the context of the procedure and or a user handling error during loading.
