title: Modified ab externo method for introducing 2 polypropylene loops for scleral suture fixation of intraocular lenses.
abstract: We describe a method that enables the introduction of 2 suture loops for scleral fixation of an intraocular lens (IOL) by a single ab externo procedure. A long needle carrying a polypropylene suture loop is inserted through the scleral fixation site and docked with a hollow needle inserted through the opposite fixation site. The hollow needle pulls the suture needle out, but the suture loop end is left external. Another polypropylene suture loop is placed through the first loop. As the first (leading) suture is pulled, the second (trailing) suture is drawn into the eye. The suture loops are retrieved through the main incision. The IOL haptics are secured with a polypropylene loop by cow hitches. After the IOL is placed in the eye, the sutures are fixated to the sclera. This technique enhances efficiency and control during the introduction of suture loops for scleral fixation of IOLs.
