A report is given on the implantation of 500 Medallion lenses, most of which were implanted after intracapsular cataract operation (88%) and were kept under observation for between 3 and 88 months (average 22 months). In 1.2% a severe keratopathy resulted from an operation that was too traumatic, from decentration of the lens or because of postoperative wound rupture. Apart from these events, however, the behavior of the lens was excellent. The track record showed that late complications - particularly those involving the iris and cornea - did not occur in cases in which the operation and postoperative course had been uneventful. Therefore, late complications are unlikely to occur in such eyes. In our opinion the Medallion lens is still an excellent implant although modern posterior chamber lenses might offer certain advantages.
