Using black diaphragm intraocular lens implantation in management of traumatic aniridia combined with aphakia in order to eliminate the severe symptom of photophobia and to improve visual acuity. Methods:Black diaphragm intraocular lens produced by Morcher Company (Germany) was used in 37 cases of traumatic aniridia combined with aphakia due to cataract extraction or lensectomy and vitrectomy for the first or secondary lens implantation (suture fixation). Results:Certain degree of improvement in photophobia symptom and visual acuity are observed in all cases after surgery. Conclusions:Black diaphragm intraocular lens implantation is an effective technique with practical prospect in management of traumatic aniridia combined with aphakia,yet the post surgery complications should be noted.
