Alternative Method for Sulcus Fixation of Posterior Chamber Lenses in the Absence of Capsular Support

Abstract

The realization that posterior chamber intraocular lenses have many advantages over anterior chamber ones has induced many practitioners to try methods of fixating the lenses in the ciliary sulcus when there is inadequate capsular support. Most of these methods require the use of sutures to anchor the lens to the sclera or the iris. We describe a modification of these techniques which allows the surgeon to place a stiff all-polymethylmethacrylate (PMMA) lens in the sulcus in a way that makes it unnecessary to anchor the lens, although a safety suture may be placed through the scleral lip. We believe this modification makes sulcus fixation simpler to perform and possibly safer for the patient. We have used this technique in six patients with good results.
