Event Description
|
A nurse reported that during an intraocular lens (iol) implantation procedure, there was challenges with the plunger but surgeon decided to use the device anyway.The device was prepared normally according to instructions and pushed plunger forward and noticed that plunger was sliding on top of the lens.The technician pulled the plunger back and asked the surgeon to check the lens.The surgeon inspected the lens and said the lens could still be used.The surgeon pushed plunger forward and this time plunger pushed the lens forward as it should.The lens was placed in the eye but the trailing haptic of the lens was not properly folded inside the lens but was stuck between the plunger and the tip of the delivery system.Lens was freed from the delivery system with forceps.The lens remained undamaged and the lens was fitted to the eye.The surgeon had used forceps was used to remove the haptic from between the injector tip and plunger.The lens remained undamaged and the lens was fitted to the eye using an auxiliary instrument.The is no patient harm was reported.No further information available.

Manufacturer Narrative

We are unable to determine the root cause for the reported complaint "plunger override.".Sample was not returned for evaluation.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 ovds 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 23°c / 73° 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.The reported trailing haptic issues cannot be confirmed, however they most likely occurred due to re-use of the lens post plunger override observation.Ifu (instructions for use) does not instruct to re-use the device.In addition to this, the ifu instructs: "visually inspect the lens to determine the position of the leading and trailing haptics.Verify that the plunger is in contact with the trailing optic edge." based on the results from the product history record, the products met release criteria.The manufacturer internal reference number is: (b)(4).
