Abstract
The aberrations for anterior corneal surface, posterior corneal surfaceand complete eyes are measured and calculated. The aberrations for thecrystalline lens are obtained by subtracting the aberrations in corneafrom that in complete eyes. It is shown that the combination betweenthe crystalline lens and the cornea can be either a compensatory or anadditive process. The combination between the anterior and theposterior corneal surfaces on the aberrations is complicated,compensatory or additive. The anterior corneal surface contributesmainly lower-order aberrations (astigmatism) of images, while theposterior corneal surface and the crystalline lens contribute mainlyhigher-order aberrations.
