We introduce a technique for iris fixation of a posterior chamber intraocular lens (IOL) in which most of the procedure is done outside the eye. This minimizes intraocular manipulation, maximizes corneal endothelial preservation, and avoids the risk for IOL drop into the vitreous cavity intraoperatively. The IOL is fixated to the most peripheral part of the iris, resulting in a rounder pupil. Sutures are placed at exact positions on the haptics, resulting in a well-centered IOL.

Several methods have been devised to implant an intraocular lens (IOL) in the absence of capsule or zonule support, including the use of anterior chamber IOLs (AC IOLs) (angle-supported or iris-claw) and posterior chamber IOLs (PC IOLs) with iris or scleral fixation. Endothelial cell damage with AC IOL implantation is a significant concern.1, 2 Therefore, in the presence of low endothelial cell function or when Descemet-stripping automated endothelial keratoplasty (DSAEK) is performed concurrently, iris fixation of a PC IOL may be preferred even though this may also have complications.3 Iris fixation of a PC IOL has the advantage of being closer to the nodal point and rotiational axis of the eye.4 We introduce a technique for iris fixation of a PC IOL with a low complication rate.
