Additional Manufacturer Narrative

The product was not returned.Product history records were reviewed and documentation indicated the product met release criteria.The product investigation could not identify a root cause for the reported complaint.The product remains implanted.Each lens is subjected to a 100percentage assessment of the power (spherical and cylinder) and optical resolution during the manufacturing process in order to determine acceptability per the lens model and diopter.It is unknown if the lens is at the correct axis.Per the instructions for use (ifu) misalignment of the axis of the lens versus the intended axis of placement may compromise its astigmatic correction.Such misalignment can result from inaccurate keratometry or marking of the cornea, inaccurate placement of the toric iol axis during surgery, an unanticipated surgically induced change in the cornea, or physical rotation of the toric iol after implantation.In order to minimize this effect, the surgeon should be careful to ensure that preoperative keratometry and biometry is accurate and that the iol is properly oriented prior to the end of surgery.The ifu also instructs carefully remove all viscoelastic from both the anterior and posterior sides of the lens.Residual viscoelastic may cause complications including lens rotation resulting in misalignment of the company model toric trifocal uv absorbing iol with the intended axis of placement.The ifu instructs that rotation of the company model iols toric trifocal uv absorbing iol away from its intended axis can reduce the astigmatic correction.Misalignment greater than 30 degrees may increase postoperative refractive cylinder.If necessary, lens repositioning should occur as early as possible prior to lens encapsulation.The reporting health care provider indicated they were not the implanting surgeon.The reporter feels the issue is related to higher order aberrations.Requested file be sent to global quality customer affairs.File will be reopened if new information or the sample is received.The manufacturer internal reference number is: (b)(4).
