aGöz Kliniği, İzmir Atatürk Eğitim ve Araştırma Hastanesi, İZMİR Objective: To determine the safety and the efficacy of surgical implantation of artificial iris-lens with black diaphragm in patients with congenital and traumatic aniridia.
Material and Methods: Eight eyes of 6 consecutive patients who have congenital or traumatic aniridia enrolled in this study. Two patients with congenital aniridia had a surgery of both eyes, the other 4 had unilateral traumatic aniridias and had a surgery in one eye. The opaque diaphragm surrounding the transparent optic aniridia IOL, made of PMMA, in one piece was implanted to all patients (Morcher GmbH, model 67F and Ophtec 311 Aniridia Lens). This type of IOLs with fixation holls on haptics were implanted in the sulcus for congenital aniridias and 2 of the traumatic cases that have enough capsular support. In the other 4 with traumatic aniridias, the IOLs were transsclerally sutured through a 10 mm midlimbal tunnel incission. In the study, while paying attention on the complications that can occur during surgery or after the surgery, the visual results were evaluated objective and subjectively.
Results: Best corrected visual acuity (BCVA) improved in all of the eyes, glare and photophobia decreased in all of the eyes except one patient postoperatively. In 1 of the patients visuel prognosis delayed because of the occured ciliary sulcus bleeding during surgery. But none of the complications including; persistant intraocular inflamation, severe and long standing intraocular pressure elevation, IOL decentration and hyphema were seen postoperatively.
Conclusion: Although in our experience the diaphragm diameter is too large and cannot be implanted with small incision, it appears sufficiently safe and provided satisfactory functional results for correction of posttraumatic, congenital and functional aniridia. Also improving BCVA and reducing glare and photophobia in most patients make valuable these IOLs. Five mm optical diameter seems enough. More cases and longer follow up are needed to assess clinical performance properly.Keywords: Aniridia; intraocular lens; cataractTurkiye Klinikleri J Ophthalmol 2007, 16:9-14
