Two 10-0 nonabsorbable surgical (Prolene) sutures used to preplace an iris loop and a loop around the intraocular lens eyelet are sutured together at the 9-o'clock position. The intraocular lens is repositioned by anchoring the iris sutures at the 12-o'clock position. This technique allows one to avoid an explantation of the lens and implantation of a new intraocular lens.

The extensive surgical manipulations that were necessary in the early days of cataract extraction and intraocular lens (IOL) implantation tended to weaken the integrity of the lens capsule, leading to frequent cases of decentration and . . . [Full Text of this Article]
