Abstract
in English, German

The functional results and the occurrence of side effects (especially photic phenomena) for multifocal intraocular lenses (IOL) are difficult to predict. Furthermore, in the course of life patients can develop diseases in which a multifocal optic would be a disadvantage. In these cases exchange of the IOL is the only treatment option. Implantation of a monofocal or monofocal toric IOL in the capsular bag and a supplementary trifocal IOL in the ciliary sulcus in a single operation, known as a duet procedure, provides trifocality that can be easily reversed if necessary.

Funktionelle Ergebnisse und das Auftreten von Nebenwirkungen (insbesondere photischer Phänomene) können beim Einsatz multifokaler Intraokularlinsen (IOL) schwer vorhergesagt werden. Des Weiteren können Patienten im Laufe des Lebens Erkrankungen entwickeln, bei denen eine multifokale Optik von Nachteil sein kann. In diesen Fällen ist ein Austausch der IOL die einzige Therapieoption. Die Implantation einer monofokalen oder monofokal-torischen IOL in den Kapselsack und einer additiven trifokalen IOL in den Sulcus ciliaris in einer als Duett-Verfahren bezeichneten Operation ermöglicht Trifokalität, die bei Bedarf vergleichsweise einfach wieder rückgängig gemacht werden kann.

Keywords: IOL exchange; Presbyopia; Sulcoflex; Supplementary IOL; Trifocal IOL.
