Abstract
- The factors determining refractory power are axial length, corneal power and lens power. The author investigated the correlation between axial length and refractory power by research for growing process of axial length in Korean children. The mean values of axial length are obtained by ultrasonography (A-scan) after cycloplegic refraction. The subjects of study were 245 children, 483 eyes, from 4 to 14 years old. The study revealed that axial length increased by aging and axial length change to refractory power tends to lengthen with increasing degrees of myopia, shorten with increasing degrees of hyperopia. Statistical analysis of the research show that the phenomenon is presented remarkably in patients of over-4 diopter.
