With regard to this complaint, a pouch with a blue particle was received.Neither the involved phaco needle nor any other product was returned for investigation.Based on its color and texture, microscopic examination revealed that the light blue particle (2.13 mm x 0.54 mm) is determined to be plastic.Therefore, the particle could not have originated form the phaco handpiece, the phaco needle or the phaco sleeve.The color and texture of the particle were compared to blue plastic dorc product that is used during cataract surgery.Colors of the eva cartridge, the infusion tubing connector and the dorc 2.2 mm slit knife did not match the color of the particle and could not have been the source.In fact there was only one product that appears to match with the color of the particle and that was a 2.2 mm slit knife from a competitor.As we have not received information regarding the use of competitor product during the operation, the latter could not be confirmed.Review of the device history records related to the reported lots revealed no deviations.
