Abstract

The distribution of refractive errors and its relationship to the optical components in 105 Hong Kong Chinese aged 19–39 years was studied. Myopia was most frequent (71%) in this population. The mean spherical equivalent was ‐3.00 DS. The trend of changes of the direction of refractive and corneal astigmatism from with‐the‐rule to against‐the‐rule with increasing age was shown. Significant correlations were found between age and anterior segment distance. Ultrasound examination showed that an increasing axial length was associated with higher myopia. Men had flatter corneal radii, but longer axial length. The prevalence of myopia in the Chinese population seems to be a new trend for the younger Hong Kong Chinese when compared with adults aged over 40 years. Thus the importance of genetics in determination of myopia is called into question by these findings.
