title: Model for co-ordination of corneal and crystalline lens power in emmetropic human eyes.
abstract: A mathematical model is used to investigate the co-ordination of corneal and crystalline lens power in emmetropia. Modelled depth changes of the anterior chamber, crystalline lens and vitreous chamber were based upon empirical data. Modelled power changes of the corneal and crystalline lens were then purely governed by eyeball shape. Power changes generated by the model closely agreed with empirical data indicating that the co-ordination of both, to maintain emmetropia, can be accounted for by relative axial and equatorial growth of the eyeball.
