The lens was returned positioned incorrectly in the lens case.Solution was dried on the lens.Both haptics were bent in the gusset and distal area.One haptic was adhered by solution to the anterior optic surface.The optic was pressed between two posts of the lens case.Upon return, the lens was observed to be placed into the lens case incorrectly resulting in damage.The lens was removed from the lens case and cleaned with klrp for further evaluation.Once klrp was administered both haptics and optic went back to their original shape.Both haptics were pliable when manipulated.A dimensional inspection was conducted.The lens met specifications per the approved template.A device history record review and a non-conformance review of the reported lot number was conducted.The deviation review did not reveal any potential contributing factors to the reported complaint and all corresponding production release specifications defined in the device master record were met.The cartridge and handpiece information were not provided.It is unknown if qualified products were used.The file indicated the use of a non-qualified viscoelastic.The product investigation could not identify a root cause for the reported event.Bent haptics were observed that may have occurred due to how the lens was positioned in the lens case for return.The lens was removed from the lens case and cleaned with klrp for further evaluation.Once klrp was administered both haptics and optic went back to their original shape.Both haptics were pliable when manipulated.A dimensional inspection was conducted.The lens met specifications per the approved template.Due to being returned inside the lens case, it is not possible to confirm the reported bent haptic upon loading complaint.The customer indicated the use of a non-qualified viscoelastic which could be a contributing factor.It is unknown if a qualified cartridge and handpiece were used.The ifu instructs: company foldable iols are qualified for use with a 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.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.Clareon ifu: follow the section regarding directions for use for information on the maximum allowed time for the iol to stay in the folded condition.Failure to adhere to manufacturer¿s recommendations may result in iol damage.Ifu note: during lens loading and insertion, do not allow the clareon iol to remain in a folded condition within the selected iol delivery system for more than 3 minutes prior to completing insertion into the capsular bag.The handpiece ifu instructs: 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.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).
