title: Experience with the large circular loop medallion lens and a critical comparison with the suture medallion lens: a report of 300 cases.
abstract: An iris-supported intraocular lens must have stable fixation to minimize postoperative complications. A series of 46 large circular loop Medallion lenses were implanted after intracapsular cataract extraction and compared with a series of 254 suture Medallion lenses. An unexpectedly high incidence of lens dislocation and iris damage occurred with the large circular loop Medallion lens implants. Based on our results, we believe that the large circular loop Medallion lens should not be used for implantation after intracapsular cataract extraction at this time. The suture Medallion lens provides a standard to which other pseudophakai may be compared.
