Additional information was provided in h.3.,h.6 and h.11.The product was not returned for analysis.Only photo was returned.Plunger override was observed on the returned photo.Photo provided shows an activated company pre-load device.The plunger appears to be advanced into mid nozzle and appears to be advanced over the intraocular lens (iol).The iol appears to be advanced into the mid nozzle.We are unable to determine the root cause for the reported complaint plunger went over top of lens and did not advance it.The product was not returned for analysis.Plunger override was observed on the returned photo.Plunger override may occur: if the lens has become misaligned in the lens bay during the manufacturing process.Due to the use of a non-qualified viscoelastic.Material properties of non-qualified ophthalmic viscosurgical device (ovd) may contribute to underfill, overfill, misfolding of the haptics, or other inconsistent folding outcomes.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 the lens.If the operating room temperature is too high (greater than 23 degrees centigrade / 73 degrees fahrenheit) 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.Based on the results from the product history record, the products met release criteria.The manufacturer internal reference number is: (b)(4).
