Additional information was provided in h.3., h.6.And h.11.The product was not returned.A photo was provided.The photo showed the used device on top of the carton.The device was on its side with the door facing out.The lens stop and plunger lock had been removed.The plunger was oriented correctly.Viscoelastic was visible in the device.The plunger has been retracted.The lens was visible beside the device on the top of the carton.No other determination can be made due to the viscoelastic on the lens.A batch record review and a non-conformance review of the reported lot number was conducted.The deviation review did not reveal any potential contributing factors to the reported complaint and all corresponding production release specifications defined in the medical device file were met.A qualified viscoelastic was indicated.The root cause for the reported lens damage could not be determined.The product was not returned.The provided photo showed the device with the plunger oriented correctly with viscoelastic visible in the device.The lens was outside of the device.No other determination can be made due to the viscoelastic on the lens.It is difficult to make a final determination without evaluation of the physical sample.The root cause cannot be determined based on available information.Fully insert the opthalmic viscoelastic 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 ml of ovd.Only use a company ovd qualified for use with the pre-loaded delivery system that has been allowed to come to the operating room temperature.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.Take at least 7 seconds to gently fold the intraocular lens (iol) by advancing the plunger forward in one smooth, continuous motion until the front edge of the optic is even with the ¿fill-to¿ line on the nozzle.Do not allow any portion of the lens to exit the nozzle tip.At this position the blue spring will contact the clear main body.It is important to not advance the plunger abruptly to fold the iol as improper folding and lens damage may occur.After the lens has been advanced to the nozzle line, the lens should be visually inspected to determine the position of the haptics.The plunger should be in contact with the trailing optic edge.After confirming the lens is properly positioned and the haptics are folded properly, proceed with lens implantation.Proceeding with implantation of a misfolded haptic or a lens that appears to be ¿out of position¿ can result in a broken haptic or other negative outcome, since the haptic may be trapped and stretched, and/or pinched and sheared by the moving plunger.The investigation has been completed based on current information.Receipt of additional relevant information or supporting materials will prompt a re-evaluation of the complaint investigation.Complaints are reviewed and monitored for adverse trends on a monthly basis.No adverse trends have been observed associated with the reported product and event.No further action has been identified for this reported event.Quality assurance has reviewed this complaint and will continue to monitor data for evidence of adverse trending and take further action, as appropriate.No further action warranted at this time
the manufacturer internal reference number is: (b)(4).
