Methods: Eleven eyes of 6 patients with congenital aniridia have been operated from 2007 to 2013. There were 1 male (2 eyes) and 5 females (9 eyes) aged from 16 to 57 years. Follow-up period was from 3 to 68 months. Congenital aniridia was associated with cataract of various degree in 11 eyes, 7 eyes of 4 patients had ptosis of the upper eyelid, and in 4 eyes there was nystagmus. Before surgery corrected visual acuity was from light perception to 0.2 (mean, 0.07). Mean IOP was 19.6 mm Hg. Endothelial cells density ranged from 2,300 to 3,142 cells/mm2. Shirmer’s test did not show a significant decrease of tear production.

Results: For aniridia correction we used single piece Artificial iris + IOL complex manufactured by Reper NN Russia. The complex includes optic part, with the diameter of 3.5 mm. and painted, peripheral part. The overall diameter of the block is 13 mm. After phacoemulsification through a 2,2 mm corneal incision, the incision is enlarged up to 5.0 mm. The complex is implanted on the capsular bag using forceps without additional fixation. No inflammation signs were seen. Corrected Visual acuity has improved in all cases (from 0.1 to 0.6). In 7 cases there was an IOP elevation treated medically in 6 cases and after glaucoma surgerie in 1 case. The cornea was intact. Shirmer’s test was normal in 8 eyes, slightly decreased in 2 eyes and significantly decreased in 1 eye. All the patients use artificial tears. All the patients are satisfied with cosmetic result and mark that optical effects associated with the absence of diaphragm function of the pupil have disappeared. One female patient had uneventful pregnancy and delivered a child 60 months after the operation.

Conclusions: Correction of congenital aniridia using “Artificial iris + IOL” complex showed good cosmetic and functional results in long-term period, promoting social rehabilitation of patients. Increased intraocular pressure is the most common event in the postoperative period that requires monitoring IOP level and corneal status control.
