A 27-Gauge Trocar-Assisted Intrascleral Intraocular Lens Fixation Technique Using a Silicone Microtube

Abstract

Purpose: This study aimed to describe a novel technique to facilitate intrascleral fixation of the intraocular lens (IOL). Methods: Two 27-gauge trocars were placed at an angle of 180° and a distance of 2 mm from the corneal limbus. A silicone microtube with an external diameter of 0.2 mm was introduced through a sclerocorneal incision and withdrawn via a trocar using retinal forceps. The tips of the IOL haptics were connected to the microtube. After the implantation of the IOL into the chamber, the haptics were externalized through the scleral site by pulling the microtubes. Each tip of the haptics was flanged and buried into the scleral tunnel. Results: The IOL was successfully placed with this method without any complications. Conclusion: This study presented a novel technique for intrascleral IOL fixation using a silicone microtube. We believe that our technique might increase surgical safety and help decrease the operative time for both anterior and posterior segment techniques.
