Abstract
DO.07.04 The optical quality of the human eye: what is desirable, what can be achieved? Preußner P.-R.
Univ.-Eye-Hospital Mainz Corneal refractive surgery and improvements in IOL development try to optimize human visual quality. The theoretical limits of these improvements are not yet achieved in reality. Nevertheless, an ideal, diffraction limited optical quality as e.g. in an space telescope will never be achievable. For physiological reasons, the eye is too unstable. Further, optical errors occuring at one location (cornea or lens) cannot be fully corrected on the corresponding other location (lens or cornea) already for fundamental, physical reasons. Physiological, physical and technical limits of aspheric, toric surfaces are quantified for monochromatic and polychromatic light. This should be the basis to destinguish desirable developments and pure marketing actions from each other.
