Event or Problem Description
A healthcare professional reported that during an intraocular lens (iol) implantation procedure, lens was sitting correctly and when surgeon started inserting cartridge into patient's eye plunger went over the lens and started to wrap around injector and would not eject into the patient's eye and due to this haptic broke off.Procedure was completed with new lens with no harm.
Additional Manufacturer Narrative
The used cartridge was returned.Inadequate viscoelastic was observed.The lens was just past the loading area pressed up against the roof.The leading haptic was broken.The cartridge tip had a large aneurysm on the left side and heavy stress.The cartridge had evidence of placement into a handpiece.The used cartridge was cleaned for further evaluation.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 cartridge was used.The handpiece and viscoelastic used were not provided.It is unknown if qualified products were used.The root cause for the reported event appears to be related to a failure to follow the ifi.The lens was returned pressed up against the roof of the cartridge.This position would indicate a plunger underride occurred, not the reported override.In addition, a lack of viscoelastic was observed in the cartridge.The extensive cartridge tip damage would also indicate the lens/plunger were not in acceptable positions for advancement.Top coat dye stain testing was conducted with acceptable results.The ifu instructs to completely fill the cartridge with ovd immediately prior to loading and delivery of the lens.Do not attempt to load the lens without adequate ovd in the device.Not adequately filling the device with viscoelastic will result in inadequate coverage of lens and the lens fold path with ovd, which may result in damage.The ifu instructs: using holding forceps, grasp the lens by the optic edge and gently place the lens anterior side up into the back of the ovd-filled cartridge.The lens should be inserted until the optic is a little more than half-way inside the cartridge.Use the holding forceps to gently push down on the lens, verifying that the lens is on the bottom surface of the cartridge.Using holding forceps, take the trailing haptic, and gently fold the haptic onto the anterior side of the optic.Slowly grip or push the optic edge to position the lens as far into the cartridge as the forceps will permit, while ensuring the lens remains on the bottom surface of the cartridge and the trailing haptic remains on the optic.Failure to follow these steps may cause the lens to advance incorrectly causing delivery issues and/or damage.Important: the plunger should make initial contact with the cartridge at the ramp.In the event the plunger does not contact the cartridge at the ramp, do not use the handpiece and contact company.The handpiece ifu instructs: verify that the plunger tip is properly engaging the lens optic and that the lens moves forward at the same rate as the plunger while slowly advancing the plunger forward to avoid damaging the lens.When the threads on the knob make contact with the barrel, turn the knob clockwise approximately ½ turn to engage the threads and then stop.The iol will now be in the dwell position.Inspect to ensure the plunger is behind the optic.The manufacturer internal reference number is: (b)(4).
