Abstract Details

Purpose:

Describe a novel technique of implantation of PID (CUSTOMFLEXﾮ ArtificialIris)/IOL (Akreos AO60 or CUTTING EDGE Synthesis IOL) complex in one single combined surgery. The technique we describe is not previously reported in the literature making this case series unique.

Setting:

Three patients with aniridia underwent surgery for PID and IOL implantation. The first patient is 53-year old with congenital aniridia. The two other patients had traumatic aniridia. The three patients underwent successful ArtificialIris and IOL implantation using the technique described below.

Methods:

Peritomy from seven till four. Two marks nasally/two marks temporally three-millimeters from limbus. 6mm sclero-corneal tunnel at twelve oﾒclock. 3 trocars. PPV and shaving Extraocularly, squared edge IOL (Akreos AO60 or CUTTING EDGE Synthesis) put posterior to ArtificialIris. Gore-tex suture passed antero-posteriorly through artificial iris into haptics of IOL. Same suture passed postero-anteriorly through ipsilateral inferior haptic of IOL and then through ArtificialIris. Same process done on opposite side creating Iris-IOL Complex. Sclero-corneal tunnel widened to 6mm. Gore-Tex sutures passed through intended sclerotomies. Iris-IOL Complex folded and inserted into anterior chamber. Sutures tightened to sclera. Iris-IOL complex centered. Sclerotomy/peritomy closed.

Results:

The three patients described in our case series improved and recovered good visual acuity. They did not present any side effects. Vision improved from hand motion to 20/200 in the congenital aniridia patient. In the traumatic aniridia cases, vision improved from counting fingers 2m to 20/30 in the first case, and from hand motion to counting fingers in the second case due to a central corneal scar from the original penetrating trauma. All patients reported major improvement of their previous photophobia. No post operative complications were noted, last follow up being several months post operatively.

Conclusions:

We describe cases where both an artificial iris and an IOL needed to be implanted, in the absence of any sulcus support. Our technique does not need more than one surgery. Also, the square edge IOL used provides good central support for the ArtificialIris. Finally, only two scleral sutures were used 180 degrees apart, compared to the previously described technique of four scleral sutures. Thatﾒs why our technique is more time efficient compared to previously described methods and is also predictable and reliable.
