Abstract Details

Purpose:

In patients implanted with artificial iris (AI) chronic inflammation is common problem. The special suturing technique was developed to fixate AI to the sulcus. This technique can be used in aphakic as well as in pseudophakic eyes. The goal is to fixate AI to the sulcus in the way that it does not touch sulcus or posterior iris surface.

Setting:

University Eye Hospital Ljubljana,Slovenia

Methods:

Patients with posttraumatic aniridia or large iris defects were implanted with AI alone or in combination with IOL sutured to the AI. Special loop sutures were used. With lasso technique IOL was sutured to the AI and later to the sulcus using the same suture and zigzag suturing technique. Prior to implantation AI was trimmed or trephined to 10.5 mm. Before the end of the surgery the AI or AI IOL complex was centered to the anatomical axis of the globe by adjusting zigzag sutures.

Results:

Good centration of the AI to the anatomical axis of the eye was achieved. Photophobia was not a problem any more. Also aphakia could be corrected. Visual acuity (VA) improved markedly, especially in bright light and sunshine. No clinically relevant anterior chamber inflammation was noticed more than two years after surgery. No CME developed. Also in surgerie combined with penetrating keratoplasty VA improved to 0.9 and no CME was present.

Conclusions:

AI implantations in aniridia, ocular travma, aphakia and in severe iris defects is safe and effective procedure in combination with floating suturing technique. The photophobia disappears, visual acuity is improved and there is a tremendous esthetic effect. This technique does not cause inflammatory response.
