We report the results of with a ocular lens implantation in 132 cases of unilateral traumatic cataract. In most cases (130) the cataract was treated on using the extracapsular technique. Four types of intra-ocular lenses were used: Binkorst 2 loops implanted into the capsule (6%), Binkorst 4 loops sutured to the iris (18%), Anterior chamber implantation (19%), Posterior chamber implantation (57%). Implantation and cataract surgery were performed simultaneously in 85 cases (64.3%). Implantation was secondary in 47 cases (35.6%) implantation was performed as often in cases of contusion as in cases of perforating traumic, lens often in cases of intra-ocular foreign body. Implantation was usually primary in cases of contusion, now after secondary in cases of perforation. The most severe post operative complications are hypertony, corneal dystrophy (Binkorst 4 loops implantation and overall, anterior chamber lenses). Fonctional results in the child one 5 year old are about the same us in the adult. On the contrary in the child from 2 to 5, the results are bad because of the associated ocular lesions and fonctionnal amblyopia. In case of corneal associated lesions, it seems better to perform a primary implantation and eventually put the lens out of the center of the scar. Perforating keratoplasty must be reserved for cases of large central scotoma. In the cases of perforating trauma, surgery of the cataract must be differed if possible to allow simultaneous implantation.(ABSTRACT TRUNCATED AT 250 WORDS)
