The Circular Loop Intraocular Lens

Abstract

A large series of cases of intracapsular cataract extractions with implantation of the recently introduced Medallion circular loop lens is reviewed. Case selection surgical technique, postoperative management, complications and results are presented in detail. Surgical and visual results have been excellent ahd compare favorably with intracapsular cataract surgery performed without artificial lens implantation. The transiridectomy clip of the posterior supporting circular loop provides an excellent system of lens fixation and eliminates the need for an iris suture with the potential long-term complications of possible iris suture absorption. The lens is essentially unluxatable. A particularly low incidence of cystoid macular edema, as well as other long-term postoperative complications, has been encouraging. The surgical technical requirements for implantation of this particular implant are very exacting. Further refinements in design and construction of this artificial lens based on the experiences developed in this series of cases are proposed.
