Ocular component analysis by vergence contribution to the back vertex power of the anterior segment.
Refractive errors are essentially the expression of a dysfunction in a dynamic system of light vergences. It follows that the nature of the dysfunction can be studied by reference to the light vergences. However, the usual analysis deals with surface powers and their separations within the eye. These two dimensions do not express the actual functional conditions taking place within the optical system. Assessment of the optical elements and path lengths in terms of the actual vergence they produce does so. Hence, this paper presents a method using vergence to illustrate the value of such an assessment.
