Clinical Experience with Black-Diaphragm Intraocular Lens in Traumatic (Postoperative) Aniridia and Aphakia

ABSTRACT

When aniridia is associated with aphakia after trauma, traditional implantation of posterior chamber IOL has some technical difficulties owing to lack of iris support and weakness of zonule, but especially big problem lies in that it cannot satisfy improvement of symptoms such as photo phobia, epiphora and visual acuity simultaneously. For the purpose of correcting these two diseases, specially designed artificial lens (Black-Diaphragm IO-LMORCHER IOL) has been introduced and is being used currently. Black-Diaphragm IOL may have some postoperative complications such as persistent intraocular inflammation, corneal endothelial cell damage, cystoid niacular ederna, and increased intraocular pressure. On 6 patients (4 rnales, 2 females) who had aniridia associated with aphakia after trauma authors implanted Black-Diaphragm IOL into ciliary sulcus by transscleral fixation. During average of 7.3 months follow up periods, we observed corneal ederna, hyphema, vitreous hernorrhage in I eye (I case) but, in the remaining 5 eye.
