OBJECTIVE: To analyze long-term complications of black diaphragm aniridia intraocular lens (IOL) implant in traumatic aniridia and to investigate the causes and precautionary measures.
METHODS: This is a retrospective consecutive case study. Five traumatic aniridia cases undertaken black diaphragm aniridia IOL implantation in Shandong Eye Institute and Hospital and developed severe complications during long-term follow-up were analyzed, including 4 males and 1 female, averaged 26.8 years old. The follow-up time varied from 42 months to 108 months. Two cases had implantation of a secondary black diaphragm IOL after pars plana vitrectomy. Two cases had implantation of a black diaphragm IOL together with cataract extraction. One case implanted a black diaphragm IOL only.
RESULTS: All patients felt well within a short period after the surgery, symptoms of glare and photophobia were improved. A better visual acuity was obtained in a short-term period. However, severely secondary glaucoma and bullous keratopathy occurred in the long-term follow up. Visual acuity decreased to counting finger or hand motion. All cases received penetrating keratoplasty and IOL explantation.
CONCLUSIONS: Black diaphragm aniridia intraocular lens implantation may induce severe long-term complications. The indications should be selected seriously and closely follow-up is important.
