[The black diaphragm intraocular lens implantation].
OBJECTIVE
To evaluate the clinical effect of the black diaphragm intraocular lens (IOL) implantation.


METHODS
The black diaphragm IOL implantation performed on 23 cases (23 eyes) of traumatic aniridia (21 eyes) and congenital aniridia (2 eyes) was studied retrospectively.


RESULTS
Photophobia was reduced obviously and the naked visual acuity was improved in all 23 cases after the black diaphragm IOL implantation, VA > or = 0.1 in 16 cases (70%). The complications included vitreous hemorrhage (2 eyes) in the operation, and there were exudates on the surface of IOL (13 eyes), IOP elevation (3 eyes), macular hole (1 eye), recurrent retinal detachment (1 eye) and corneal decompensation (5 eyes) after the operation.


CONCLUSIONS
The black diaphragm IOL implantation provides an effective means of treating traumatic or congenital aniridia, but the indication should be strictly controlled.
