Abstract
We report a new intrascleral fixation technique for a standard 3-piece posterior intraocular lens (IOL) using catheter needles and 30-gauge ultrathin needles instead of a special forceps and minimal intraocular manipulation in eyes without capsule support. Modified catheter needles are used to deliver the IOL haptic. The IOL haptic is secured extraocularly between the cannula and needle of a catheter needle and then advanced through the sclerotomy site. Scleral tunnels are created using 30-gauge ultrathin needles, which also serve as a guide to introduce the haptics. This technique can be performed even in cases in which miosis and corneal edema prevent anterior chamber observation. The guide needle facilitates haptic insertion into the long and narrow scleral tunnels. The procedure is a good alternative to current techniques.
