[Factors affecting the visual prognosis after extraction of congenital cataract with IOL implantation].

Multivariated analysis of corrected visual acuities after extraction of congenital cataract with IOL implantation in 24 patients (41 eyes), including 14 children (22 eyes) under 12 years of age, revealed that 6 factors significantly affected the postoperative results, namely, the pattern of lenticular opacity, monocularity, strabismus, nystagmus, after-cataract formation and its time of onset. Therefore, operation as early as possible is recommended for cases with these factors and IOL implantation considered, with discretion, in children for whom other forms of visual aids are not available.
