Preliminary results following implantation of iris-suture-fixated posterior-chamber lenses.

Iris-suture-fixated posterior-chamber lenses with a 7-mm optic zone and modified C-loops with 2 holes were implanted in 30 patients (8 men and 22 women), of whom 13 received simultaneous corneal transplantations. The mean follow-up period was 13.3 months. The iris was penetrated from behind and the intraocular lens was sutured with two double-armed 9-0 prolene sutures, the knot being positioned on the anterior surface of the iris. Most patients showed an increase in visual acuity except for two who had pre-existing retinopathy and one who developed a seclusio pupillae. The complications seen were: mild distortion of the pupil (7), iris capture (1), posterior synechiae (1) and ablatio chorioideae (1). This new technique yields good results in cases of intraoperative rupture of the capsule. In patients undergoing simultaneous corneal transplantation, a longer follow-up period is needed.
