One hundred and twenty-seven eyes of children less than 15 years of age underwent keratoplasty with one to ten years follow-up. The cases were divided into three groups of age, and the results are compared. Graft transparency has a direct correlation with the age of patient and type of corneal disease. Penetrating keratoplasty carries a better surgical and visual prognosis when carried out late in childhood. This is not only the fact of the particular etiologies found in this subgroup of age. When adjusting the results to the both factors age and etiology, we have demonstrated their independent. The visual benefits of corneal transplantation in selected cases in children appear to outweigh the difficulties and problems engendred by this procedure.
