PURPOSE: Establish, for the eyes with congenital and development cataract, mathematical models to calculate the daily axial growth rate (AGR) and calculation of the axial length (Axl) in any future age, from the age and Axl measured at the time of surgery. METHODS: Retrospective study of children undergoing cataract extraction with IOL implantation between January 2011 and January 2014. We included children with uncomplicated cataract without eye diseases and the age of ten years. Biometric data were obtained with plunge biometer. We carried out the statistical analysis of data and established mathematical formulas to calculate the AGR and Axl. RESTULTS: Were operated on 54 eyes of 33 children, 19 male (57.58%) and 14 female (42.42%). Of the 33 cases analyzed, 12 were unilateral cataracts (36,37%) and 21 were bilateral cataracts (63.63%). In cases of bilateral cataracts was used only the right eye of the data of every child. The sample was divided into 3 groups (unilateral and bilateral cataracts, unilateral cataracts, bilateral cataracts) and for each group was established a mathematical formula to calculate the AGR and Axl. CONCLUSIONS: This study proposes a new way to approach the calculation of IOL, not based on postoperative refractive results but on a daily growth rate (AGR). The generated equations for establishing the daily growth rate at any age and especially to allow predict Axl future from a measured initial Axl. Can not complete with this study that the proposed method is superior to other methods of estimation of eye growth. Comparative studies between them will be needed to assess this accurately
