An evaluation of the usefulness and reliability of the Alcon Renaissance handheld keratometer within a population of children under six years of age

1 March 1995


The Alcon Renaissance handheld keratometer was evaluated for percent testable and repeatability in children under six years of age. Sixty children participated in the study. Three readings per eye were attempted for each child. For those children over two years of age, a seventy-five percent testable level or better for three readings was found. The study also indicated consistent repeatability with excellent correlations between the first reading and the mean of three readings found for the horizontal meridian (90% < 0.50D), vertical meridian (87% < 0.50D), Delta K (96% < 0.50D), and axis values (76%
