Sutureless intrascleral fixation using a uniquely designed intraocular lens

We report our experience in the surgical technique of sutureless intrascleral posterior chamber intraocular lens (PC IOL) fixation in patients with insufficient capsular support using a uniquely designed, foldable, acrylic Carlevale IOL. It is specifically designed for sutureless scleral fixation and is equipped with a small plug attached to each of two haptics to anchor the lens to the sclera with a self-retaining mechanism. This surgery does not require creation of a scleral tunnel or transscleral exposure or excessive manipulation of the haptics. The harpoon-like plugs provide great stability to this implant, which can be injected through a 2.2mm incision. The characteristics of this IOL and the relative simplicity of this implantation technique makes it widely applicable in aphakic patients after previous complicated cataract surgery.
