The lens was returned on surgical gauze.Blood and solution was dried on the lens.Both haptics were broken in the gusset area (only one broken haptic portion was returned).The optic is cut into pieces, typical of insertion and removal.Product history records were reviewed and documentation indicated the product met release criteria.The file indicated the use of a qualified cartridge with a non-qualified viscoelastic.The associated handpiece was not provided.It is unknown if a qualified product was used.The reported broken haptic was observed.The root cause for the reported lens damage may be related to failure to follow the ifu (instructions for use).The file indicated the use of a qualified cartridge with a non-qualified viscoelastic.The associated handpiece was not provided.It is unknown if a qualified product was used.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 (ophthalmic viscosurgical device) 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 (intraocular lens) delivery system for more than 3 minutes prior to completing insertion into the capsular bag.Additional information has been provided that the corneal edema has subsided, but astigmatism is thought to have increased due to suturing for wound enlargement.However, since the suture thread is absorbable, it is expected to resolve over time.No additional information has been provided.The file will be reopened if information is provided.The manufacturer internal reference number is: (b)(4).
