The lens was returned on a tissue with a triangular shaped white medical sponge with a blue handle inside a biohazard bag.Viscoelastic was dried on the lens.The posterior surface of the optic has a linear crack across the central optic zone.This damage was most likely interpreted as the reported scratch.The posterior optic surface has two areas that are gouged, one on either side of the cracked damage.There were also two small cracked lines of damage near the optic edge.Product history records were reviewed and documentation indicated the product met release criteria.Information was provided that indicated the use of a qualified cartridge and handpiece.The viscoelastic information was not provided.It is unknown if a qualified viscoelastic was used.The posterior of the optic was cracked across the central optic zone.This was most likely interpreted as the reported scratch.Additional optic damage was also observed.The root cause cannot be determined for the reported complaint.It is unknown if a qualified viscoelastic was used.The instruction for use (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 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.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.The ifu instructs: 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.The file indicated that the company 23.5 diopter lens was removed and replaced with the backup lens (company 23.5 diopter).The manufacturer internal reference number is: (b)(4).

All lenses are 100 (percentage) % inspected for cosmetic attributes and the damage exhibited by the returned complaint sample would not have met company¿s release criteria.Based on our observations, and the review of manufacturing records, 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.The manufacturer internal reference number is: (b)(4).
