Intraocular lens extraction using the cartridge pull-through technique

Abstract

Current intraocular lens (IOL) explantation techniques are limited to cutting the optic and removing the pieces through a small incision or folding single-piece acrylic IOLs using a 2-handed technique. Poor execution of IOL explantation can result in injury to intraocular structures, including the corneal endothelium and iris. The minimally invasive cartridge pull-through technique uses a cartridge for IOL implantation and new forceps optimized for secure grasping of the IOL for removal. This method involved less manipulation in the anterior chamber, thereby reducing the risks for complications such as corneal and iris injuries. A dropped IOL lying on the retinal surface can be extracted directly without lifting it onto the iris first. The cartridge pull-through technique offers a more streamlined and potentially safer approach for IOL explantation.
