[Long term complications of black diaphragm aniridia intraocular lens implant in traumatic aniridia].

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.
