Abstract
A method for changing a property of an eye uses a continuously multifocal profile that includes a component for increasing a focal depth. The method includes calculating the component for increasing the focal depth to be rotation-symmetrical. Alternatively, or in addition, the calculating is carried out so as to optimize an encircled energy criterion over an extended range of depth.
