Effect of Gender and Race on Ocular Biometry
However, these studies did not differentiate between gender or racial groups. Previous studies have shown that taller and heavier individuals have longer ALs. Tan et al3 in a study of 1845 Asian eyes, reported that for every 10 cm (3.94 inches) increase in height, AL increases by 0.30 mm. It could therefore be conjectured that as males are usually taller, this is the major cause of longer AL. However, Lim et al4 showed in 2788 Asian eyes, when corrected for height, males still had a statistically longer eye than females. Females have also been shown to have significantly smaller corneal diameters than males in a large 23,239 eye study by Hoffmann and Hütz5 but we found no other studies to support this fact.
The goal of this study was to collect large series of ocular biometry published reports to determine whether there are differences in biometric values based on gender and race that might be useful in developing more accurate IOL power formulas.
