The sample was not returned.Photos were provided of the lens inside a company cartridge.There appeared to be an inadequate amount of viscoelastic in the cartridge.There appeared to be a residue of viscoelastic along the path of the plunger in front of the lens.The lens was located between the nozzle entry and the cartridge tip.The lens appears to be misfolded, potentially with the posterior surface against the interior ceiling.The trailing haptic was visible and oriented along the interior ceiling with distal tip toward the left side of the cartridge.It cannot be determined from the photos if the trailing haptic was broken from the optic.The leading haptic could not be observed within the provided photos of the lens inside the cartridge.It cannot be confirmed if the leading haptic was broken or folded inside the lens from these photos.A sample would be necessary to make a final determination.The cartridge showed evidence of being seated into a handpiece.Product history records were reviewed, and the documentation indicated the product met release criteria.A qualified cartridge and a company handpiece were used.The viscoelastic information was not provided.It is unknown if a qualified viscoelastic was used.Based on the photos, the lens appeared to be misfolded up and there appears to be a trail of viscoelastic beyond the lens along the path of a handpiece.This may suggest that the handpiece plunger underrode the lens.The reported broken haptic damage could not be confirmed from the photos.A sample would be necessary in order to confirm the reported damage.The root cause for the reported complaint may be related to a failure to follow the instructions for use (ifu).An inadequate amount of viscoelastic appears to be present in the photos.The ifu instructs to completely fill the cartridge with ophthalmic viscosurgical devices (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: use holding forceps to 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 it is centered with or slightly past the outline etched into the top of the cartridge.Lenses with a 6.5 mm optic diameter may need to be pre-folded for easy entry into the back of the cartridge.Lens may be pre-folded by gently applying pressure to the edge of the lens while holding the central optic with forceps.The trailing haptic will extend from the proximal end of the cartridge.Position the trailing haptic to the left of the haptic post as shown in the detailed view.This will allow the plunger to go past the haptic during the initial advancement of the plunger into the cartridge.Verify the lens is positioned on the bottom surface of the cartridge.The haptic should be maintained to the left of the post when the lens is loaded correctly.Accurate positioning of the lens will decrease the potential for optic and haptic damage.It is unknown if a qualified viscoelastic was used.The ifu instructs: company foldable intraocular lenses (iols) are qualified for use with a company qualified delivery system (handpiece and cartridge) and ophthalmic viscosurgical device (ovd) combination.The ifu instructs that a 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.Haptic manufacturing is a validated process with multiple inspections to verify the quality of the produced haptic material.These inspections include a verification of the dimensional accuracy, tensile strength, flexibility and cosmetic appearance.The inspections ensure that the material meets all required specifications before it is allocated for use.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 half 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 file indicated that no sample was returning.Due diligence has been performed in an attempt to obtain further information on this event.The reporter has not responded to request for follow-up information.File will be reopened if new information is received.The manufacturer internal reference number is: (b)(4).
