This article reviews the current literature on the risks and challenges associated with intraocular lens (IOL) implantation in the ciliary sulcus.
The development of IOLs designed specifically for placement in the ciliary sulcus continues to be an area of interest for the ophthalmic industry. Currently the one-piece PMMA (polymethylmethacrylate) lens or a three-piece IOL are the best available options for IOL placement in the ciliary sulcus space. Single piece acrylic (SPA) IOLs are not designed for sulcus placement and there is growing evidence of chronic complications related to their use in the ciliary sulcus. Many of these eyes ultimately require surgical intervention, including lens exchange. Endoscopic imaging and ultrasound biomicroscopy (UBM) have enabled a better understanding of ciliary sulcus anatomy and measurements in the living eye.
