A doctor reported that following bilateral intraocular lens (iol) implant procedures, a patient experienced bilateral decreased visual acuity.Approximately one year after the initial implant procedure, the patient became a patient of the reporting doctor.The patient at that point was 6 years old with rheumatoid arthritis.The patient did present with uveitis constantly.The doctor then noticed what seemed like a layer forming on top of the iol and decided to remove the lenses.The iols were exchanged for the same model approximately 13 years after the initial implant procedures.Additional information has been requested, although the reporting doctor does not have further product information as he did not perform the surgery and the surgeon has since retired.There are two medical device reports associated with this patient.This report is for the right eye.
