H6 - type of investigation - lens work order search: no similar complaint type events reported for units within the same lot.Manufacturer narrative: a review of the device labeling was completed.Endophthalmitis is identified in the labeling as a potential adverse event following icl implantation.Per the directions for use complications and adverse reactions implantation of any evo|evo+ icl may include but are not limited to: intraocular infection and secondary surgical intervention to remove/replace the lens.The dfu states a caution: staar surgical evo|evo+ ticl and disposable accessories are packaged and sterilized for single use only.Cleaning, reuse and/or resterilization are not applicable to these devices.If one of these devices were reused after cleaning and/or resterilization, it is highly probable that it would be contaminated, and the contamination could result in infection and/or inflammation.An exact cause could not be determined as the event could be multifactorial in nature including patient and/or procedure related factors.The lens was explanted and returned.Claim# (b)(4).

B5: per updated information the patient was seen, the stitches were removed and visual acuity is 20/20 with correction.The endophthalmitis was reported to be resolved.H6: inspection of the returned device identified four particulates on the lens.External laboratory analysis was performed to determine the size and composition of the particulates identified on the lens.First particle: found to be primarily composed of cellulosic material, second particle: primarily composed of protein and fat, third particle: primarily composed of amorphous carbon, with trace elements including oxygen, sodium, chlorine, nitrogen, aluminum, sulfur, and iron, fourth particle: primarily composed of stainless steel, with trace amounts of carbon, oxygen, silicon, sodium, chlorine, aluminum, and nitrogen.Unfortunately, we were unable to conclusively identify the source of the elements found in the sem-edx and ftir analyses.H6- device history record (dhr) review: based on the results of the investigation, the dhr review indicates that the product has been manufactured within the established process parameters and there is no indication that the manufacturing and/or processing of the device contributed to the complaint issue.Claim # (b)(4).
