To study the effect of aging on astigmatism in adult Japanese. Measurements of refractive errors and keratometry were performed on 2161 randomly selected subjects (aged 40–79 years). The relation between age and the net value in diopters (D) of astigmatism was evaluated with a trend test. The relation between age and the polar value was also examined by(More)
