Nidek inc. Was under fda inspection from (b)(4) 2014. Nidek inc. Was preparing a correction report to fda and had an opportunity to discuss on our correction strategy with fda (b)(4). During a teleconference with them on (b)(4), nidek inc. Was advised by a dr in (b)(4) that a complaint relating laceration of the nose was a serious injury as she said "i don't think the firms' analysis or strategy is appropriate. I would consider any injury to the face that can cause scarring a serious injury and it is reportable. " nidek inc. And nidek co. , ltd. Determined to submit each mdr to fda based on the advice from (b)(4). We sincerely apologize we did not submit this mdr within 30 calendar days. On the other hand, our correction strategy in the draft of customer notification letter was accepted by all fda attendees in the teleconference on (b)(4). Out strategy is to provide preventive maintenance kit including hex wrench, glue and instruction for use to all customers who purchased rt-5100 or rt-3100. Nidek inc. Has already submitted recall report (2936921-4/17/2014-001-c) dated 04/17/2014 to (b)(4). Conclusion: we conclude that the root cause of falling down of near point rod (s/n (b)(4)) is due to taking off the screw for rotation limit (sb3x6) intentionally for the following reason. "we confirmed that the hinge of s/n (b)(4) which replaced was bent, so we concluded that support point of near point rod holder and hinge got excessive burden. We have been informed that screw for rotation limit (sb3x6) of bracket (s/n (b)(4)) was taken off. As a result of investigation of rt-5100 s/n (b)(4), we confirmed that the root cause of falling down of near point rod (s/n (b)(4)) is due to taking off the screw for rotation limit (sb3x6) intentionally. " it is the description about the root cause of fallen down the near point rod of s/n (b)(4). Main body can turn 360 degrees when screw for rotation limit (sb3x6) of bracket is taken off intentionally. Near point rod and bracket clash each other when main body with near point rod rotates beyond the limit. Support point of near rod holder gets excessive burden from this clash. By the excessive burden is repeated, screws (hh3x3) which hold near point rod holder are loose or come off. We conclude that this issue occurred because screw fixation of near point rod and hinge are loose, and near point rod holder falls down.
