Simplified small-incision peripheral iris fixation of an AcrySof intraocular lens in the absence of capsule support

Abstract:
In the absence of capsule and zonule support, a modified insertion technique allows simple peripheral iris fixation of a posterior chamber 3-piece acrylic intraocular lens (IOL) via a small incision for secondary implantation. A bimanual unfolding maneuver creates pupillary capture of the optic to temporarily stabilize the IOL. Peripheral modified McCannel sutures fixate the flexible monofilament poly(methyl methacrylate) haptics to the posterior peripheral iris surface, after which the optic is safely prolapsed into the posterior chamber.
