PURPOSE: To evaluate the safety and efficacy of black diaphragm intraocular lens (IOL) implantation for the treatment of congenital and traumatic aniridia. MATERIAL AND METHODS: Seven black diaphragmatic IOLs were implanted in the eyes of six patients between 1997 and 1998. There were five males and one female. The mean was 42.8 years (range, 22-54 years). Follow-up ranged from nine to 20 months (mean, 14.2 months). Traumatic aniridia was present in four eyes and congenital aniridia in three. Pars plana vitrectomy was combined with the simple outside-in method of scleral fixation of IOLs in six cases. Three of these eyes were aphakic (all with traumatic aniridia) and, in three eyes, (two congenital cases, one traumatic case) a subluxated lens was removed simultaneously. In one case of congenital aniridia with mature cataract, ECCE and ciliary sulcus implantation without scleral fixation were performed. RESULTS: There were very few complications. Ciliary sulcus bleeding occurred in two cases during scleral fixation. Transient postoperative corneal edema was observed in two eyes, raised intraocular pressure in three eyes, and dispersed blood in vitreous cavity in two eyes. All IOLs were well centered. An improvement in best-corrected visual acuity was achieved in five cases, while good preoperative best-corrected visual acuity was maintained in two cases. CONCLUSIONS: Diaphragmatic IOLs can be fixed to the sclera in cases without capsular support or can be implanted into the ciliary sulcus after ECCE. Reconstruction of 5 mm pupils and intraocular correction of aphakia enable good visual rehabilitation of patients. The combined procedure of pars plana vitrectomy and scleral fixation of diaphragmatic lenses is safe and effective in traumatic and congenital aniridia. LA: Polish
