Additional information was provided in d3., d.9., e.1., g.1., h.3., h.6.And h.11.The lens was returned advanced to the nozzle entry in a company iii (d) cartridge.Viscoelastic was observed.The trailing haptic was not tucked per the instructions for use (ifu).The leading haptic was tucked in the optic fold.The cartridge had evidence of placement into a handpiece.Product history records were reviewed and documentation indicated the product met release criteria.A qualified cartridge was indicated.The handpiece model and viscoelastic was used were not provide.It is unknown if qualified products were used.The root cause for the unfold trailing haptic appears to be related to a failure to follow the ifu.Trailing haptic placement is manual step conducted by the end user.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 viscosurgical 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.It is unknown if a qualified viscoelastic 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 manufacturer internal reference number is: (b)(4).
