Purpose Study of different factors which can change the visual prognos
is in congenital cataract. Methods One hundred seventy eyes of 100 chi
ldren with congenital cataract are operated by extracapsular cataract
extraction with limbic incision. Posterior rhexis and anterior vitrect
omy were associated in children under 2 years. Implantation was used i
n 42%, contact lens in 8 %, Other cases were corrected by glasses. The
prognostic factors studied were: uni- or bilaterality, partial or com
plete aspect of cataract, age of apparition and management, and associ
ation with other malformations. Results Only 9 eyes out of 30 with uni
lateral congenital cataracts had visual acuity greater than or equal t
o 2/10; 44.4 % of bilateral cataracts had visual acuity greater than o
r equal to 2/10; The best visual acuity was noted in progressive and p
artial cataract without associated malformations.
