Additional information was provided in a.1., b.5., d.10., h.3., h.6.And h.11.The product was not returned.Product history records were reviewed and the documentation indicated the product met release criteria.A qualified cartridge was indicated.The associated handpiece and viscoelastic information was not provided.It is unknown if qualified products were used.The product investigation could not identify a root cause for the reported complaint.The product was not returned.Based on the questionnaire response, the root cause was indicated to be "probable human error during loading process".The ifu (instructions for use) 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.A qualified cartridge was used.The handpiece and viscoelastic information was not provided.It is unknown if qualified products were 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: follow the section regarding directions for use for information on the maximum allowed time for the iol(intraocular lens) 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 company iol (intraocular lens) 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.File will be reopened if new information or the sample is received.The manufacturer internal reference number is: (b)(4).

Additional Manufacturer Narrative
|
|
Additional information was provided in d.9.,h.3., h.6.And h.11.The lens was returned for evaluation.Solution and blood were dried on the lens.The lens was cut into three pieces, typical of insertion and removal from the eye.The lens was cleaned for further evaluation.Scratches were observed on the optic.Marks were observed on both sides of the optic that are similar to those left by a surgical instrument used to grasp the lens.A used company cartridge was returned in the specimen cup with the lens.Viscoelastic was observed in the loading area and the cartridge tip.Both wing tabs were only slightly compressed.This would indicate that the cartridge was not securely seated into the handpiece prior to delivery.The tip of the cartridge has light stress lines.A scrape mark was observed on the right side of the cartridge tip.The used company cartridge was cleaned for further evaluation.Top coat dye stain testing was conducted with acceptable results for the presence of top coat.Internal damage was observed with disruption in the coating on the right side of the tip.Product history records were reviewed and the documentation indicated the product met release criteria.A qualified cartridge was returned with the lens.The handpiece and viscoelastic information was not provided.It is unknown if qualified products were used.Lens damage and cartridge damage was observed.All lenses are 100% inspected for cosmetic attributes and the damage exhibited by the returned complaint sample would not have met company¿s release criteria.Based on our observation, it can be reasonably concluded that the damage is not manufacturing related.Due to the presence of surgical solution and the condition of the returned sample, the damage is most likely related to customer handling.It is unknown if qualified products were used.It is unknown if a qualified handpiece and viscoelastic were used.The cartridge did not appear to have been fully seated in a handpiece.The may have caused the lens/plunger to advance incorrectly.Per the ifu(instructions for use): 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 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.Company 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 company 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.File will be reopened if new information is received.The manufacturer internal reference number is: (b)(4).
