OBJECTIVE: To study the corneal curvature in Thai children, from newborn to ten years. MATERIAL AND METHOD: The authors reviewed keratometric reading of Thai children obtained from January 1st, 2003 to December 31st, 2005. Data was analyzed in stratified pattern based on their age groups. RESULTS: 360 eyes from 183 patients were enrolled. The keratometric reading (K) was ranged between 43-44 diopters, there was no statistically significant difference among mean K in all age groups (ANOVA, RE p = 0.612, LE p = 0.608). There was no correlation between absolute corneal astigmatism of each age group and age (Pearson correlation, RE r = -0.20, p = 0.006, LE r = -0.11, p = 0.11). The most common corneal astigmatism was with the rule type in all age groups. CONCLUSION: The keratometric reading was consistent in all age groups in the range between 43-44 diopters. There was no correlation of absolute corneal astigmatism and increasing age. With the rule astigmatism was the most common corneal astigmatism.
