Manufacturer Narrative
|
The lens has not been returned for evaluation.Photos provided of the lens while still inside the patient¿s eye have been reviewed and the reported product concern has been confirmed.There have been no similar events reported for this lot to date.According to the product quality engineer, it is possible that too much pressure was inadvertently applied to the lathe while it was running.The lathes are very sensitive to vibration and application of pressure may result in lathe lines.Therefore the most probable root cause is manufacturing.A nonconformance has been created for this event.A follow-up report will be submitted upon completion of the investigation.

Event Description
|
It was reported that during the implant of an intraocular lens (iol), the surgical duration was increased.The reason for this is unknown.Approximately 4.5 months post-implant damage and rings were observed on the surface of the iol with the patient reporting a loss of vision.The iol was explanted and replaced with a lens of the same model and diopter.Though requested, no additional information has been received.

Manufacturer Narrative
|
Photo's provided of the lens while still inside the patient's eye have been reviewed and the reported product concern has been confirmed.The iol was returned and visual inspection found that the optic was torn.Microscopic examination was performed and found that concentric rings were visible on the optic.Additional investigation identified several factors that could have resulted in lathe lines (lathe tool marks) on the iol.However, the root cause of the lathe marks could not be conclusively identified.The identified possible root causes are related to monitoring of the lathes while work is in process and correct use of the reticle during the cosmetic inspection process.A nonconformance was created for this event.As these require employee action, training was developed to address the issues and the training was provided to all lathing operators and cosmetic inspectors.There have been no similar events reported for this lot to date.A review of the device history record found no nonconformities or anomalies related to this complaint.There is no indication that any additional product is impacted.The history review performed for the nonconformance indicated that for the last five years, a failure to detect lathe lines during cosmetic inspection occured approximately once in every 911,000 lenses.Due to the low frequency, no product action (hold or recall) was deemed necessary.No further corrective action is necessary at this time.The investigation is complete.
