Additional Manufacturer Narrative
|
|
Additional information provided in d.9., h.3., h.6.And h.11.The device and the lens were returned in the carton.The plunger lock and lens stop have been removed.The plunger was oriented correctly.Inadequate viscoelastic was observed in the device.The plunger has advanced the lens beyond mid-nozzle and has underrode the lens.The optic was misfolded up on the right side.The trailing haptic was misfolded across the plunger and advanced underneath the lens.The leading haptic was extended back into the optic fold.The nozzle was removed and cleaned for further evaluation.The lens was removed during cleaning.Top coat dye stain testing was conducted with acceptable results.Product history records were reviewed and documentation indicated the product met release criteria.A qualified viscoelastic was indicated.The lens optic and trailing haptic were misfolded due to the plunger underride.This was most likely interpreted as the reported complaint.The root cause for the reported complaint may be related to a failure to follow the instructions for use (ifu).Inadequate viscoelastic was observed.The ifu instructs: fully insert the ophthalmic viscosurgical device (ovd) cannula, perpendicular to the device, through the viscoelastic port, located in the lens stop portion of the device.Fill the device until ovd can be observed flowing to the fill-to line on the nozzle tip.This will require approximately 0.2 milliliter of ovd.Only use a company ovd qualified for use with the company pre-loaded delivery system that has been allowed to come to the operating room temperature.Plunger underride may occur: 1) due to rapid advancement faster than the ifu recommended rate.2) 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 override/underride the lens.3) if the operating room temperature is too high (greater than 23 degree c / 73 degree f) lens folding consistency is negatively affected, the lens is more adherent and this may inhibit lens advancement.Any of the above listed causes alone, or in combination, may create the reported event.Top coat dye stain testing was conducted with acceptable results.File will be reopened if new information is received.The manufacturer internal reference number is: (b)(4).
