The device with the lens was returned loose in the carton.The plunger lock and lens stop have been removed.The plunger is oriented correctly.Only a small amount of viscoelastic is observed in the device.The plunger has been retracted to mid-nozzle.The device tip has severe damage (bent, twisted, stress lines, aneurysm).The lens was returned on the exterior of the device barrel.The optic is scratched.All product and batch history records are quality reviewed prior to product release.A qualified viscoelastic was used.The lens was returned placed on the exterior of the device.The device tip has extreme damage.The root cause of the event may be related to a failure to follow the dfu.Inadequate viscoelastic was observed in the device.The dfu instructs: fill the device until viscoelastic can be observed flowing to the line on the nozzle tip.This will require approximately 0.2 ml of viscoelastic.If inadequate viscoelastic is placed in the device this will cause inadequate coverage of the lens fold path which may cause the lens to advance incorrectly or become ¿stuck¿ in the device allowing the plunger to underride the lens.The extreme tip damage most likely is the result of the indicated "several attempts" to remove the lens from the device.Information provided in the file indicates that: an implant remained stuck in injector, with no possibility to remove it after several attempts.The manufacturer internal reference number is: (b)(4).
