OBJECTIVE To present a surgical approach for the treatment of unstable anterior chamber intraocular lenses (ACIOLs). METHODS We present a series of 8 patients who underwent iris fixation of an unstable open-looped ACIOL associated with progressive corneal damage. The loops of the intraocular lens were firmly fixated to the iris using 9-0 or 10-0 polypropylene sutures. In 2 cases, iris fixation was associated with penetrating keratoplasty. The other cases were performed using a relatively closed-system technique. RESULTS All procedures were uneventful, with no intraoperative or postoperative complications. Suture fixation effectively prevented anterior-posterior or propelling movement. The ACIOLs in all cases were stable and well centered at the end of follow-up. CONCLUSIONS Fixation of an existing unstable angle-supported ACIOL to the iris is an effective and simple alternative to intraocular lens exchange and posterior chamber fixation.

D007498	Iris	The most anterior portion of the uveal layer, separating the anterior chamber from the posterior. It consists of two layers - the stroma and the pigmented epithelium. Color of the iris depends on the amount of melanin in the stroma on reflection from the pigmented epithelium.
