Siepser slipknot for McCannel iris-suture fixation of subluxated intraocular lenses.

In 8 cases that presented with symptomatic posterior chamber IOL subluxation, a McCannel polypropylene (Prolene) suture was used with the Siepser slipknot technique to successfully refixate the IOLs to the iris. There were no intraoperative complications, and a round pupil was preserved in all cases.
