The situation is different with the latest generation of multifocal lenses:
The optics of the multifocal lenses is this way as to even young people suffering from severe defective vision and patients beyond the ages of 40 are enabled to see clearly both at a distance and within close range. In most cases they do not need any glasses after surgery any more. In contrast to commonly used artificial lenses in this case a variety of optical principles are combined and therefore a very good quality of contrast-sharpness and depth of sharpness are obtained. The technique of apodisation creates a soft blending between proximity and distance, minimises scattering effects and optimises light yield.
Even very distinctive astigmatisms can be exactly corrected by the means of this so called toric multifocal lenses.
