LAS VEGAS — Sulcus implantation of artificial irises may cause dislocation, according to a presentation at the American Society of Cataract and Refractive Surgery meeting.

However, the issue is “manageable,” Michael J. daSilva, MD, said.

“Partial or complete aniridia can be a challenging consequence of surgical or nonsurgical trauma or congenital disease,” daSilva said. “We have considerable experience with implantation of iris devices at UCLA, but little is known about the stability of these devices when they are passively fixated in the ciliary sulcus.”

DaSilva and colleagues reviewed 69 eyes of 65 patients who received the HumanOptics artificial iris. Thirty-three of these patients had passive sulcus fixation of the artificial iris.

Of those 33 patients, three devices were dislocated secondary to zonular instability, two of which dislocated at the 1-month postoperative visit.

DaSilva said that this dislocation can occur in a “small percentage of eyes with zonular damage.”

“Our study is descriptive in nature, and we hope that it will in the future allow for comparison of decentration rates for other fixation methods,” he said.
