title: Intracorneal correction of aphakia: paraxial approach at null incidence.
abstract: The technique of intracorneal implantation, recently proposed by de Laage de Meux and Cinquin [Implants, 2, 26 (1984)] for the correction of aphakia, is analyzed in terms of geometrical optics. The analysis is done by using matrix optics and by assuming a null incidence. The characteristics (diameter, radii of curvature, axial thickness) of the hard or soft lens to be implanted are determined and given. The aniseikonia of such lenses is shown to be nearly the same as that of contact lenses.
