Abstract
The results of the ultrasonographic measurements of the ocular components in 100 emmetropic eyes [human] of nearly the same age, were presented and the possible relations between the various ocular parameters were discussed. A definite correlation was found between the eye length and the curvature radius of the anterior corneal surface; between the eye length and the anterior chamber depth; and between the eye length and the vitreous length. No correlation could be demonstrated between the lens thickness and the eye length. This fact showed that in the wide range of axial eye lengths in emmetropic eyes, the emmetropization effect of the lens can only be provided by a change in the curvature radius of the lens surfaces. The mean eye length of 100 emmetropic eyes was 23.37 mm.
