Additional information provided in h.3., h.6.And h.11.Photos were provided, all showing the same image of a lens inside the eye.The lens optic area has a shadowed area near the central optic zone which may be lens damage.Due to the clarity of the photo, a determination could not be made regarding the reported lens damage complaint.A qualified cartridge and viscoelastic were indicated.The handpiece information was not provided.It is unknown if a qualified handpiece was used with the lens/cartridge combination.Based on our observation of the attached photos, the lens optic may be damaged.It is difficult to make a final determination without evaluation of the physical sample.The root cause cannot be determined based on available information.A sample would be necessary to make a final determination.The product was not returned.It is unknown if a qualified handpiece was used.The (instructions for use) 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: using holding forceps, grasp the lens by the optic edge and gently place the lens anterior side up into the back of the (ophthalmic viscoelastic device) 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.The company 18.5 diopter (1.5 extended depth of focus) lens was removed and replaced with an identical model and diopter lens.File will be reopened if new information or the sample is received.The manufacturer internal reference number is: (b)(4).

Additional information provided in d.9., h.3., h.6.And h.11.Corrected information provided in d.10.Photos were provided, which showed the same image of an implanted single-piece lens.A short, dark line was visible at the center of the lens.This may be a scratch or a crack, unable to determine if this is damage or if this on the anterior or posterior surface from the photos.The lens was returned in a vial in an unknown liquid.One haptic was broken-gusset area, not returned.The optic was cut into two pieces across the center of the optic.The cut was across the dark line visible in the photos.Due to this a determination cannot be made.Other damage was observed, scratches and scraped areas, which were not in the provided photos.This appears to be damage related to the lens removal.Product history records were reviewed and the documentation indicated the product met release criteria.A qualified handpiece and viscoelastic were indicated.The cartridge was stated to be unknown.Photos were provided, all showing the same image of a single piece lens implanted in the eye.A short, dark line was visible at the center of the lens.This may be a scratch or a crack.Due to the clarity of the photo, a determination could not be made.Unable to determine the line was on the anterior or posterior surface.The returned lens had been cut into pieces across the dark line in the photo.Due to this, a determination for the pictured dark area could not be made.Other damage was observed, scratches and scraped areas, which were not in the provided photos.This appears to be damage related to the lens removal.It is unknown if a qualified cartridge was 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.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).
