A healthcare professional reported that the injector created small and always peripheral tears in the optic edge.At most, these tears would extend 0.75 mm towards the center of the lens.The tears usually seemed to be near the haptic.The tears started happening around september and would happen with multiple technicians loading the lenses.Physician did see it happen on non-toric and toric iol¿s.Phyisician never exchanged an iol as physician could not imagine these peripheral tears being optically active.Physician did rotate a trifocal non-toric iol so the tear went down to 6 o'clock.No science to that, it just seemed sensible.Also stated physician can only imagine it was due to something new with the iols or the cartridge.Physician use a cartridge with a 2.4 mm dual bevel keratome.

The product was not returned.Complaint history and product history records could not be reviewed because the reporter did not provide a lot number or any identification traceable to the manufacturing documentation.Viscoelastic was not provided.It is unknown if a qualified viscoelastic was used.The model/diopters of the lenses used were not provided.It cannot be determined if a qualified combination was being used with the qualified handpiece.The product investigation could not identify a root cause for the reported complaint.The product was not returned.Not enough information was provided for further investigation.It is unknown if a qualified viscoelastic and lens model/diopter were being used.The ifu instructs: company foldable iols are qualified for use with an company qualified delivery system (handpiece and cartridge) and ophthalmic viscosurgical device (ovd) combination.The ifu instructs that an company qualified delivery system and viscoelastic combination should be used.The use of an unqualified combination may cause damage to the lens and potential complications during the implantation process.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.Lens damage may occur if the lens and/or plunger are not in acceptable positions for advancement.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).
