Abstract:
In eyes with absent or insufficient capsule support, three-piece posterior chamber intraocular lens (PC IOL) may be fixed to the sclera. Previous techniques involve the use of sutures, flaps, glue, needles, trocars, or intrascleral tunnels to fixate the distal tips of the haptics intrasclerally. Herein we describe a modified technique for the sutureless scleral fixation of a standard 3-piece PC IOL using self-sealing sclerotomies created with a crescent blade and a 20-gauge microvitreoretinal blade, and then reinserting the haptics to leave the tips inside the vitreous cavity. We believe the relative simplicity of this technique makes it widely applicable for the placement of an IOL with insufficient capsule support.
