The reference c240546 has been allocated to this case by rayner.The patient underwent implantation of a rayone toric rao610t on (b)(6) 2023.At examination on (b)(6) 2024, it was observed that one of the iol haptics had entered the sulcus.The patient had a secondary procedure performed to reposition the iol within the capsular bag.Decentration, tilt and rotation are known complications associated with cataract surgery and iol fixation.While it is not possible to establish the definitive root cause in this case it is possible to consider the following as potential contributory factors which may have resulted in the reported event; incorrect/unstable iol fixation within the capsular bag at time of iol implantation, irregular capsular bag contraction, residual ovd in capsular bag (cbds) and lens not fitting the anatomy of the eye.Our review of production records for the rayone toric rao610t batch 072196790 showed that all manufacturing and quality checks were conducted with successful results.All devices released for distribution from this batch were within tolerance, met specification criteria and were without defects.A review of vigilance data confirms that this is an isolated event.No other incidents, of any type, have been received against the rayone toric rao610t batch 072196790.There is no evidence of a device-related cause for the post-operative change in iol fixation within the eye.
