Retro iris suture fixation of a rigid intraocular lens

J Cataract Refract Surg. 2016 Nov;42(11):1556-1561. doi: 10.1016/j.jcrs.2016.09.011.


We present an iris suture fixation technique for a rigid poly(methyl methacrylate) (PMMA) intraocular lens (IOL). A 10-0 polypropylene suture on a long curved needle is used to preplace 2 iris suture bites 180 degrees apart. The suture loops below the iris are retracted through the main scleral tunnel using a Kuglen hook and a McPherson forceps. The 2 suture loops are twirled twice around the corresponding haptics of a standard 3-piece PMMA IOL, and the IOL is placed in the sulcus. After it is confirmed that the loop surrounds the haptic, the suture knot is tied to secure the IOL to the iris.
