In the study by Grosvenor, axial length showed a decreasing trend after age 20 years, and more specifically, subjects older than 50 years had axial length that was 0.6 mm shorter on average than the subjects aged from 20 to 29 years. 14 In our results, the hyperopic tendency in older subjects was statistically significant ( P < 0.05) even after axial length and corneal curvature were taken into account.
