The reference (b)(4) has been allocated to this case by rayner.The event description provided states that post-operatively the patient's spherical visual outcome was not as expected post-operatively.The target refractive outcome was -0.4 but the result is -4.0 just shy of one month post-operatively.The patient medical history received identified that the patient had previously twice undergone hyperopic lasik in the subject eye.Lens explantation and exchange is planned.No device has been received by rayner for evaluation.Surgical outcomes can be influenced by many factors including but not limited to; incorrect product selection, aniseikonia combined with unsuitable lens power selection and wrong lens power caused by incorrect biometry readings/calculations, toric axis misalignment, posterior synechiae, irregular capsular bag contraction, residual ovd in capsular bag (cbds), lens does not fit anatomy of eye, prior lasik surgery, incorrect cylinder power selection by surgeon and surgically induced corneal changes."deviation in target refraction" is listed in the "adverse events" section of the rayone ifu.Despite efforts made by rayner to obtain additional information to facilitate further investigation, no ufrther information has been forthcoming.While it is not due to establish the root cause of the deviation in target refraction from the limited information available, it is possible that the patient's prior lasik surgery has impacted the final refractive outcome in this case.
