| Abstract |
|
Cogenita aniridia is a relatively rare congenital anomay and its incidence is about 1:100,000. It occurs along with cataract(85%) and nystagmus(92%). Black diaphragm intraocular lenses(IOLs) were inserted in five eyes of congenital aniridia with cataract. Nystagmus was seen in all eyes, while lens subluxation was observed in two eyes. The IOLs were inserted into the ciliary sulci in two eyes with lens subluxation, and the capsular bag in three eyes. In all testing eyes, we tested preoperative and postoperative visual acuity, intraocular pressure, and preformed routine ocular examinations. We also examined multivision contrast test(MCT) in two eyes. Postoperative visual acuity improved in all cases, but the intraocular pressure increased only in one eye. The nystagmus slightly decreased in all cases. The result of postoperative MCT was the same as that of preoperative. But in the other cases, the glare decreaed. By insertion of the black diaphragm IOL, we achieved the improvement of visual acuity, the decrease of glare and nystagmus, and cosmetic effect. |
