Abstract Details

Purpose:

To evaluate the efficiency and safety of bright Ocular iris prothesis in cases of aniridia associated with aphakia or cataract.

Setting:

Private Center/EyeCare Center Maadi ,Cairo,Egypt.

Methods:

Retrospective study of surgical managment and clinical course of 5 eyes of 4 patients in the duration between 2012 and 2014. Age range from 12-34 years old.All cases had large iris defects . 2 eyes of same patient with congenital aniridia and cong cataract.Three eyes with traumatic aniridia one with subluxated cataractous lens and 2 aphakia.Phacoaspiration (or Scleral fixation of 3 piece IOL)and iris prothesis(silicone material) implantation with done .Follow up period from 6-24 months.out come measures included intraoperative problems,postoperative visual acuity corneal clarity,IOP,iris prothesis centeration,cosmetic satisfaction of the patient and any other complications during the follow up .

Results:

There was no intraoperative complications. All patients had improved UCDVA and BCDVA as compared to preoperative status. Except for one eye there were transient increase in IOP needing medical treatment. Only the congenital case suffered from a permenant increase in IOP after 6 weeks. the same patient had after 6 months a form of band keratopathy in both eyes.; all cases had a transient mild corneal oedema in first 2 days that resolved and remained clear through out the follow up period.the prothesis was well centered in all eyes except for one case that was markedly displaced after 3 months and required a fixation scleral suture. All patients had very satisfacory cosmetic apperance

Conclusions:

Bright ocular iris prothesis is a useful tool to correct aniridia. The technique is simple and safe. Being foldable makes it east to use a small incision.The implant if properly sized can rest in front of the Posterior chamber IOL in the sulcus without sutures.Cosmetic results are satisfactory. IOP increase is a concern but could be related to the aniridia itself. It is effective method to correct aniridia with aphakia. Sizing methods should be improved. The prothesis in this small study group was safe.Larger study is needed.
