PURPOSE. To evaluate the axial length (AL), anterior chamber depth (ACD) and lens thickness (LT) of eyes of full-term infants with congenital and development cataracts uncomplicated and provide specific estimates by age. METHOD. Retrospective study of children undergoing cataract surgery between June 2011 and January 2014. Children with uncomplicated cataract without ocular pathologies and less than ten years old were included. Biometric data were obtained with immersion biometer. Proceeded to statistical analysis and linear regression with logarithm of age to model the relationship of AL with age. RESULTS. All eyes of 41 children were included in the analysis, with a mean age of 37.3 months. Age had a significant relationship with measures of AL (p< 0.01). 23 were male (56%). Had a mean age of 32.1 months for males and 44 months in females, with low ratio of AL according to gender (p>0.05). The mean and standard deviation of AL in eyes with unilateral cataract surgery (n=16) and randomly selected one eye in bilateral cases (n=25) were 20.37 ± 2.11 mm and 20.54 mm ± 1.97 respectively. AL measures had a positive linear relationship with ACD and LT . Eyes with unilateral cataract had smaller AL than the contralateral healthy eyes. CONCLUSION. AL measures change significantly with age, especially in the first six months. The study predicts values of AL in various age groups, contributing to the calculation of intraocular lens power in children
