Standard, “monofocal” IOLs deliver optical correction for just one distance. Usually this power is selected to correct the patient’s distance vision, with spectacles being used to see objects in the intermediate to near distance.
This limitation is eliminated by modern multifocal Diffractiva® IOLs that feature special optical properties to enable the patient to see clearly at all required distances without any additional visual aids. After a successful operation and a completed healing process, normal everyday life can be resumed, for the most part without glasses.
Most of the time near sighted skills like reading take place in bright light conditions and thus with constricted pupil diameters. In these conditions, only the IOL´s inner, central ring-structure is utilised which improves near vision.
In this way the Diffractiva® is ideally adjusted to the respective, variable light condition and thus enables comfortable vision during the various activities of daily life.
