Manufacturer Narrative

Reporting of this complaint at this time is based on receipt of a letter from the fda dated april 10, 2008 in which the agency informed alcon that complaint (event date: 2006) should have been reported as a serious injury mdr. As a result of that injury report, a 2-year reporting timeframe was initiated for all complaints of the same type. All complaint files for the ladarvision4000 were reviewed for this type of event starting the same day. This mdr filing is a result of that retrospective review. Determination of root cause: assessment: while on-site, the field service engineer (fse) was unable to duplicate the laser not firing issue, but was able to identify the event in the surgery database. As part of the testing performed, the fse verified the thyratron was not prefiring or skipping. No parts were replaced or returned for eval. The fse completed a successful sys verification. Conclusion: based on this investigation and the results of prior investigations, the event was consistent with normal behavior of the thyratron technology and the root cause is most likely related to the thyratron.
