Management of a displaced angle-supported anterior chamber intraocular lens.

A 49-year-old patient had a displacement of an anterior chamber intraocular lens (IOL) producing a cyclodialysis cleft and persistent hypotony with maculopathy. The patient underwent intraocular lens extraction, repair of the cyclodialysis cleft, and iris-fixation of an acrylic posterior chamber IOL with resolution of the hypotony and improvement of the maculopathy and best-corrected visual acuity. Many surgeons consider the implantation of an anterior chamber IOL as their first choice in the treatment of inadequate capsule support associated with cataract surgery, probably because it is a relatively easy procedure to perform. However, insufficient preoperative knowledge of the anterior segment biometry can lead to inadequate lens size and postoperative complications.
